Help:CirrusSearch/pl

CirrusSearch is a new search engine for MediaWiki. The Wikimedia Foundation migrated to CirrusSearch since it features key improvements over the previously used search engine, LuceneSearch. Ta strona opisuje funkcje, które zostały dodane lub zmienione w porównaniu do starszych rozwiązań.

Najczęściej zadawane pytania
Jeżeli nie ma tutaj odpowiedzi na twoje pytanie, zapytaj na stronie dyskusji, a ktoś na nie odpowie.

Co zostało ulepszone?
Nowa wyszukiwarka oferuje trzy istotne ulepszenia w stosunku do starej wyszukiwarki, są to:


 * Lepsza obsługa wyszukiwania w różnych językach.
 * Szybsze aktualizacje indeksu wyszukiwania, znaczące zmiany na stronach zostają szybciej uwzględnione w wynikach wyszukiwania.
 * Expanding templates, meaning that all content from a template is now reflected in search results.

Aktualizacje
Aktualizacje indeksu wyszukiwania są wykonywane niemal w czasie rzeczywistym. Użytkownik powinien móc wyszukać swoje zmiany tuż po ich dokonaniu. Zmiany w szablonach powinny być widoczne na stronach wykorzystujących te szablony już po kilku minutach. Zmiany w szablonach korzystają z kolejki zadań, więc wydajność może nie być stała. Pusta zmiana strony wymusi natychmiastową zmianę, ale nie powinna być konieczna, jeśli wszystko przebiega prawidłowo.

Podpowiedzi wyszukiwania
Podpowiedzi, które uzyskujesz podczas wpisywania zapytania w polu wyszukiwania, w postaci rozwijanej listy polecanych stron, to zasadniczo strony posortowane względem liczby linków wskazujących na nie. Warto zauważyć, że jeśli rozpoczniesz zapytanie znakiem ~, podpowiedzi nie wyświetlą się podczas wpisywania, i możesz w dowolnej chwili nacisnąć Enter, aby przejść do wyników wyszukiwania.

Pomijanie ASCII/akcentów/znaków diakrytyczncych jest włączone dla tekstu po angielsku, ale występują pewne problemy z formatowaniem wyników. Zobacz 52656.

Wyszukiwanie pełnotekstowe
Wyszukiwanie pełnotekstowe (które kieruje cię na stronę wyników wyszukiwania), wyszukuje w tytule, przekierowaniach, nagłówkach i tekście stron, więc nie powinno powodować niespodzianek. Duża zmiana polega na tym, że szablony są rozwijane.

Stemming – wyszukiwanie wyrazów o wspólnym rdzeniu
Istnieje wsparcie dla kilkudziesięciu języków, ale należy nim objąć wszystkie języki. Lista aktualnie wspieranych języków jest dostępna na elasticsearch.org; zobacz ich dokumentację dotyczącą współpracy, aby dodać wymagania lub poprawki.

Filtry (intitle:, incategory: and linksto:)


W porównaniu do starszej wersji doprecyzowaliśmy składnię filtrów.


 * intitle:foo
 * Find articles whose title contains foo. Stemming is enabled for foo.
 * intitle:"fine line"
 * Find articles whose title contains fine then line. Stemming is enabled. Matches The finest (lines) but not The finest ever lines.
 * intitle:foo bar
 * Find articles whose title contains foo and whose title or text contains bar.
 * -intitle:foo bar
 * Wyszukuje strony, których tytuł nie zawiera foo, a których tytuł albo tekst zawiera bar.
 * intitle: foo bar
 * Błąd składni, wyszukuje strony, których tytuł albo tekst zawiera intitle:, foo i bar.
 * incategory:Muzyka
 * Wyszukuje strony znajdujące się w kategorii Muzyka.
 * incategory:"historia muzyki"
 * Wyszukuje strony znajdujące się w kategorii Historia muzyki.
 * incategory:"musicale" incategory:"1920"
 * Wyszukuje strony znajdujące się jednocześnie w kategorii:Musicale i kategorii:1920.
 * -incategory:"musicale" incategory:"1920"
 * Wyszukuje strony nieznajdujące się w kategorii:Musicale, a znajdujące się w kategorii:1920.
 * zam*
 * Wyszukuje strony, których tytuł albo tekst zaczyna się na zam.
 * linksto:Pomoc:CirrusSearch
 * Wyszukuje strony, które linkują do strony Pomoc:CirrusSearch.
 * -linksto:Pomoc:CirrusSearch CirrusSearch
 * Wyszukuje strony, które zawierają tekst CirrusSearch, ale nie linkują do strony Pomoc:CirrusSearch.

prefix:
The prefix: syntax in its current form is relied upon for a great deal of functionality so it's been recreated as exactly as possible.

Note that the old rule of having to put prefix: at the end of the query still applies.

Specjalne prefiksy

 * Find articles whose text is most similar to the text of the given articles.
 * The  query works by choosing a set of words in the input articles and run a query with the chosen words. You can tune the way it works by adding the following parameters to the search results URL:
 * : Minimum number of documents (per shard) that need a term for it to be considered.
 * : Maximum number of documents (per shard) that have a term for it to be considered.
 * : Maximum number of terms to be considered.
 * : Minimum number of times the term appears in the input to doc to be considered. For small fields this value should be 1.
 * : Minimal length of a term to be considered. Defaults to 0.
 * : The maximum word length above which words will be ignored. Defaults to unbounded (0).
 * (comma separated list of values): These are the fields to use. Allowed fields are,  ,  ,  ,   and.
 * ( | ): use only the field data. Defaults to : the system will extract the content of the   field to build the query.
 * : The percentage of terms to match on. Defaults to 0.3 (30 percent).
 * Example:
 * These settings can be made persistent by overriding  in Help:System message.
 * Find articles in the talk namespace whose title or text contains the word foo
 * Find articles in the file namespace on this wiki and commons whose title or text contains the word
 * You can add  to the query (like  ) to remove the results from commons
 * Find articles in the file namespace on this wiki and commons whose title or text contains the word
 * You can add  to the query (like  ) to remove the results from commons
 * You can add  to the query (like  ) to remove the results from commons
 * You can add  to the query (like  ) to remove the results from commons

"Did you mean" suggestions are designed to notice if you misspell an uncommon phrase that happens to be an article title. If so, they'll let you know. They also seem to suggest more things than they ought to sometimes.

Prefer phrase matches
If you don't have too much special syntax in your query we'll give perfect phrase matches a boost. I'm being intentionally vague because I'm not sure exactly what "too much special syntax" should be. Right now if you add any explicit phrases to your search we'll turn off this feature.

Fuzzy search
Putting a ~ after a search term (but not double quotes) activates fuzzy search. You can also put a number from 0 to 1 to control the "fuzziness" fraction, e.g. nigtmare~.9 or lighnin~.1 or lighnin~0.1. Closer to one is less fuzzy.

Phrase search and proximity
Surrounding some words with quotes declares that you are searching for those words close together. You can add a ~ and then a number after the second quote to control just how close you mean. The default "closeness" is zero. One means one extra word allowed, and so on. For more than two words in the phrase, the closeness equals the total number of extra words, provided that all the words are also in order left to right.

For the closeness value of words given in right to left order, count and discard all the extra words, then add twice the the total count of remaining words minus one (in other words, add twice the number of segments). For the full proximity algorithm, see Elastic Search.

An explicit AND is required between two phrases because of the "inner" quotation marks.

Quotes and exact matches
Quotes turn on exact term matches. You can add a ~ to the quote to go back to the more aggressive matcher you know and love.

prefer-recent:
You can give recently edited articles a boost in the search results by adding "prefer-recent:" to the beginning of your search. By default this will scale 60% of the score exponentially with the time since the last edit, with a half life of 160 days. This can be modified like this: "prefer-recent:,". proportion_of_score_to_scale must be a number between 0 and 1 inclusive. half_life_in_days must be greater than 0 but allows decimal points. This number works pretty well if very small. I've tested it around .0001, which is 8.64 seconds.

This will eventually be on by default for Wikinews, but there is no reason why you can't activate it in any of your searches.

hastemplate:
You can find pages that use a certain template by adding the filter  to the search. We provide for the usual "syntactic sugar" of template calls. This means the lenient pagename and fullpagename capitalization works, and the main namespace abbreviation, ":" works. For example to find which pages transclude Quality image the full search (in all your preferred namespaces) can be: , and for that same template name in the main namespace, this works. You can omit the quotes if the template title does not contain a space. will filter pages that do not contain that template.

For wikitext that calls a template directly, you can use insource:, but hastemplate: searches the "post-expansion inclusion", so hastemplate: can find a template acting only temporarily as a "secondary template" or "meta-template", which are seen in neither the source nor content, ( but only included as a helper to any other template producing the final content). All content from a template is now reflected in search results is still the relevant philosophy here.

boost-templates:
You can boost pages' scores based on what templates they contain. This can be done directly in the search via  or you can set the default for all searches via the new   message. replaces the contents of  if the former is specified. The syntax is a bit funky but was chosen for simplicity. Some examples:


 * Find files in the China category sorting quality images first.
 * Find files in the China category sorting quality images first.


 * Find files in the China category sorting quality images first and low quality images last.
 * Find files in the China category sorting quality images first and low quality images last.


 * Find files about popcorn sorting quality images first and low quality images last. Remember that through the use of the  message this can be reduced to just.
 * Find files about popcorn sorting quality images first and low quality images last. Remember that through the use of the  message this can be reduced to just.

Don't try to add decimal points to the percentages. They don't work and search scoring is such that they are unlikely to matter much.

A word of warning about : if you add really really big or small percentages they can poison the full text scoring. Think, for example, if enwiki boosted featured articles by a million percent. Then searches for terms mentioned in featured articles would find the featured articles before exact title matches of the terms. Phrase matching would be similarly blown away so a search like  would find a featured article with those words scattered throughout it instead of the article for Brave New World.

Sorry for the inconsistent  in the name. Sorry again but the quotes are required on this one. Sorry also for the funky syntax. Sorry we don't try to emulate the template transclusion syntax like we do with.

insource:
This can pick up template arguments, URLs, links, html, etc. It has two forms, one is an indexed search, and the other is regex based.

Tip: Instead of running a bare insource:/regexp/, these return much much faster when you limit the regexp search-domain to the results of one or more index-based searches.





Any search without a namespace or prefix searches your default search domain, settable at Special:Search. It is commonly reset by power users to ALL namespaces, but if this occurs for a bare regexp search, it will probably incur an HTML timeout.

Regex are character-wise per-page searches.

All other search terms use an index. When using a regex, include other search terms to limit the regex search domain as much as possible.

To develop a new regexp, or refine a complex regexp, use  in any edit box. This limits the regexp search domain to the current pagename. Use  to test your regexp on a few pages.

Metacharacters
This section covers how to escape metacharacters. For the actual meaning of the metacharacters see the explanation of the syntax.

For the formal definition see the Lucene grammar for regular expressions.

The use of a regexp to search for an exact string that includes non-alphanumeric characters is a basic search. It finds regular expression metacharacters literally by placing the entire regexp inside double quotation marks, which blindly "quotes" or "escapes" any possible metacharacters from their advanced search meaning. An advanced search usually escapes metacharacters one at a time with a backslash. For example  matches a '2', a literal plus sign, an equals sign, a '4' and a literal dot. (The equals sign has no special metacharacter meaning in CirrusSearch, and so need not be escaped.) But a basic search always simply "quotes" any characters using double-quotes inside a regexp because this will neutralize all metacharacter meanings, and perform a basic, exact-string search:  finds that string exactly in the source wikitext. A backslash-escaped character (or, equivalently, a double-quotes enclosed character or characters) always matches itself.

Inside double quotes you must use backslash-escape to escape a double-quote character, for example:

Inside the regexp you must use the backslash-escape to quote any slash character that is not delimiting the regexp, for example:

The square-bracket notation for creating your own character-class also escapes metacharacters. To target a literal right square bracket in your character-class pattern, it must be backslash escaped, otherwise it can be interpreted as the closing delimiter of the character-class pattern definition. The first position of a character class will also escape the right square bracket. Inside the delimiting square brackets of a character class, the dash character also has special meaning (range) but can it too can be included literally in the class the same way as the right square bracket can. For example both of these patterns target character that is either a dash or a right square bracket or a dot:  or.

Advanced example
For example, using metacharacters to find the usage of a template called Val having, inside the template call, an unnamed parameter containing a possibly signed, three to four digit number, possibly surrounded by space characters, AND on the same page, inside a template Val call, a named argument "fmt=commas" having any allowable spaces around it, (it could be the same template call, or a separate one):



It is fast because it uses two filters so that every page the regexp crawls has the highest possible potential.

Assuming your search domain is set to ALL, it searches the entire wiki, because it offers no namespace or prefix.

Auxiliary text
Cirrus considers some text in the page to be "auxiliary" to what the page is actually about. Examples include table contents, image captions, and "This article is about the XYZ. For ZYX see ZYX" style links. You can also mark article text as auxiliary by adding the  class to the html element containing the text.

Auxiliary text is worth less than the rest of the article text and it is in the snippet only if there are no main article snippets matching the search.

Lead text
Cirrus assumes that non-auxiliary text that is between the top of the page and the first heading is the "lead in" paragraph. Matches from the lead in paragraph are worth more in article ranking.

Commons search
By default when the search contains the file namespace, Cirrus will search commons as well. You can disable this behavior by adding  to the search. If you are using a namespace prefix to select the namespace the syntax looks like. If you aren't using a namespace prefix to select the namespace then the syntax looks like.
