Questions, comments

 * If it's just a different improved enterprise wrapper around lucene, then why would search results be any different? (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * Primarilly because Solr brings a different set of plugins and a different scoring strategy. We know we'll be different - we'd like to be better. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))


 * About the URLs served by solr for each collection of documents. Are these URLs internal, or will it be visible to wiki users? (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * Some of those urls are administrative and shouldn't be exposed to the public (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))
 * The actual search is probably safe to expose but I think we should do more research before doing so. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))


 * Most stuff we'll test in labs. Will the labs instance(s) show search results for a live wikipedia(s)?  I hope so, otherwise people won't be motivated to test. If so, you could even change the messages on the live wiki's Special:Search page to add "Repeat this search against our new search engine in testing" (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * I like the "Repeat this search against our new search engine in testing" quite a bit and think we should go for it if it isn't a ton of work. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))
 * We've been testing against restores (via mwdumper) of enwikiquote, a nearly empty wiki full of test data, and jawiki in labs. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))


 * When you roll out to mediawiki.org and other wikis, will there be a similar "Problems with these search results? Try using the old search engine, _report_ any cases where it's worse." (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * This sounds like a great way to get more feedback. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))
 * I agree. It could be a link to a translatable help page here on mediawiki.org, containing also instructions on how to report issues/give feedback. Such links usually work quite well. --Nemo 16:12, 18 June 2013 (UTC)
 * Will Solr have any more or different features than current search? (According to Help:Searching there are currently no features except the Special:Search page's checkboxes for category selection and including redirects) (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * The plan for CirrusSearch is to replace what we have in the first release and then build on it. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))


 * Is CirrusSearch a PHP plug-ins or Solr plugin? Can you link to its code? Similarly, there is no link or explanation of MWSearch and lsearchd. (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))
 * PHP. Added links. (NEverett (WMF) (talk) 20:52, 17 June 2013 (UTC))


 * Formatting: Use sentence case for headings, hyphenate three-word phrases (like "three-word phrases"): home grown search, full text search, space delimited languages, etc.


 * It sounds fine, thanks for working on this. (S Page (WMF) (talk) 19:19, 17 June 2013 (UTC))


 * Will it be possible to have an interwiki search again (44420) at some point? Is it easier with Solr than with Lucene? --Nemo 07:05, 18 June 2013 (UTC)


 * How is the scoring going to be? Will it replicate the current Lucene scoring (which considers number of incoming links and the like) or not, and will it be easier to adjust gradually as needed in the future (as opposed to the current monolithic scoring nobody understands, impossibile to tailor)? --Nemo 07:05, 18 June 2013 (UTC)


 * "Will transcluded pages be able to be indexed in situ especially where the pages are transcluded cross-namespace, or would this be part of a future build?": I don't understand the question nor the answer (yes to which of the two?). My question: will it index the pages with all templates expanded? This is particularly important for Wiktionary, but also Wikisource and Wikipedia. --Nemo 07:05, 18 June 2013 (UTC)


 * If I remember correctly, MWSearch uses customized tokenizers in indexing. Will these be ported to the new solr search? --Mglaser (talk) 10:02, 18 June 2013 (UTC)
 * And how easy will it be to implement new ones? --Nemo 16:10, 18 June 2013 (UTC)
 * I absolutely love the faceted search feature of Solr. Are there any plans to use this one? I think this might have to be reflected in building the schema. --Mglaser (talk) 10:02, 18 June 2013 (UTC)
 * A search for categories would be so great! In BlueSpice, when indexing the articles, we also store their categories. On the scale of our wikis, this is very performant. Would you think this might also be an idea at this large scale? --Mglaser (talk) 10:02, 18 June 2013 (UTC)
