Extension talk:MWSearch

What are the advantages/disadvantages of MWSearch extension over Lucene extension ? Thank you.

MWSearch is being maintained and developed, while LuceneSearch is not. The difference are minor. MWSearch has a somewhat better and more consistent interface, e.g. it has galleries for Image namespace hits. --Rainman 15:01, 24 April 2008 (UTC)

Does MWSearch support Windows + Apache / Windows + IIS ?
 * No, the search backend does not support windows. --Rainman 13:52, 12 May 2008 (UTC)
 * thats not true; i just managed to compile it under ubuntu and now running it on a windows 2003 server --193.27.220.82 13:55, 28 May 2008 (UTC)

MWSearch over SSL?
Is it possible to use MWSearch over SSL? If so, is there a special configuration needed? (I ask b/c I've been unable to get it working and I'm not permitted to open additional ports)
 * Sorry to answer my own question, but I was able to make this work by editing my host file to point the domain to 127.0.0.1 instead of the external IP. I don't really like this solution so I'm hoping this isn't the preferred method. Does anyone have any suggestions?

MediaWiki_SVN+Lucene-Search2_SVN+MWSearch_SVN = ZERO search results
I've been trying for a very long time now to implement Lucene-search functionality on my MediaWiki site -- I've spent Hours+Days+Weeks+Months troubleshooting this very issue - I'm giving this one last effort, I am hoping SOMEONE will be able to help me, otherwise I am thinking of moving away from MediaWiki entirely (which would make me a very sad panda), and will painstakingly import my MediaWiki into Drupal - then try out their neat sounding-module called Drupal::Search_Attachments module. I have put in over 1 year's worth of work into my MediaWiki-based wiki. I truly need the solution that Extension:Lucene-search+Extension:MWSearch offers, but it has been next to impossible for me to implement on my Slackware server. Who knows, my trouble could very well be something I am doing wrong! I'm human enough to admit that if it turns out to be the case... This is why I come for assistance, I am thinking of posting to the MediaWiki forums too, and linking here (hope that's OK), as I really, really want to get Extension:Lucene-search+Extension:MWSearch working for me! I have been trying to get Extension:Lucene-search+Extension:MWSearch working for over 6months now, and posted alot of my previous issues HERE at the MediaWiki Lucene-Search Talk page, but was unable to find any solutions to my problem. I even tried the newer+more-up-to-date Extension:Lucene-search+Extension:MWSearch setup to no avail. I am BACK, now with a brand new computer (well, it's actually older-hardware, but newly formatted hard-drive), a freshly installed OS, a very basic website with some basic data input to test search functionality This is my current overall system setup; I've gone over and over and OVER the directions per Extension:Lucene-search and Extension:MWSearch pages, I just cannot get this working properly on my box, now that I tried on a new install with new everything, I am convinced this is not a problem on my end, but I could be wrong --- I have documented EVERYTHING I did from install, to now since I've been over this so many times, maybe by me posting my logs here and what I did from begining to end, someone might "see something" I'm missing?? Please HELP! =)

The actual PROBLEM is NO SEARCH RESULTS
Now that I have everything setup, and Lucene-search2-deamon running I tried to search on my website... Fingers crossed.... I type in a known word that IS on the front page, and is also in my XML dump of the MySQL DB (wikidb.xml) --- sure enough, I get ZERO SEARCH RESULTS!! I get this error in my MediaWiki search results page; Search results From AgentDcooper's Wiki You searched for wiki For more information about searching AgentDcooper's Wiki, see Searching AgentDcooper's Wiki. Showing below 0 results starting with #1. No page text matches Note: Unsuccessful searches are often caused by searching for common words like "have" and "from", which are not indexed, or by specifying more than one search term (only pages containing all of the search terms will appear in the result).

Troubleshooting the ZERO results issue
Since I have a console session open with lucene-search2 daemon running, I notice that AS SOON as I hit the SEARCH button after typing in my search phrase (loopback) in my MediaWiki search box, the lucene-search2 daemon console output scrolls the following; 893553 [pool-2-thread-1] INFO org.wikimedia.lsearch.frontend.HttpHandler  - query:/search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10 what:search dbname:svnwikidb term:loopback 893567 [pool-2-thread-1] INFO org.wikimedia.lsearch.search.SearchEngine  - Using NamespaceFilterWrapper wrap: {0} 893592 [pool-2-thread-1] INFO org.wikimedia.lsearch.search.SearchEngine  - search svnwikidb: query=[loopback] parsed=[contents:loopback (title:loopback^6.0 stemtitle:loopback^2.0) (alttitle1:loopback^4.0 alttitle2:loopback^4.0 alttitle3:loopback^4.0) (keyword1:loopback^0.02 keyword2:loopback^0.01 keyword3:loopback^0.0066666664 keyword4:loopback^0.0050 keyword5:loopback^0.0039999997)] hit=[1] in 12ms using IndexSearcherMul:1214736931039


 * I've been troubleshooting this issue for a long time, so I do know how to enable Mediawiki Debuging --- here is what my /var/log/mediawiki/debug_svn_log.txt shows ;;

 * That is the part I am having the most trouble with, IMHO!
 * Follow me here.... Everything actually seems to work, up until the 3rd to last line in the debug! The part that doesn't appear to be working properly is the 3rd from the bottom line =  total [0] hits.
 * This is my reason, WHY I think that is the case, If I actually pull up the web address on my webserver via lynx or any other webbrowser =  http://localhost:8123/search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10  I get the following output!

1 1.0 0 Main_Page


 * That output appears to be saying that THERE IS 1 page that matches!!! The page being Main_Page??!! Does that sound right?? I suspect something MUST be wrong here, it has been pointed out that it may be my CURL library, but that was on an earlier version of Slackware (12.0, I am now running 12.1) - according to my Slackware 12.1 (plain vanilla install, except I upgraded to newer version of PHP) the CURL version/package I am using is curl-7.16.2-i486-1. I don't suspect that CURL is my problem, but I am completely open to anyone's interpretation of my issue at hand, and would love to work with someone on this, and/or come up with a solution... I think it's working, just MWSearch is not passing the data properly to my MediaWiki search???

Does anyone have any ideas here? Please help me, I really don't want to move away from MediaWiki, but I very much need this functionality from MediaWiki! Thanks in advance + sorry to be longwinded, just wanted to ensure I give as much details as possible - if you have any questions, feel free to ask!

PS :: I tried ExtensionFunctions.php SVN-06-25-2008
BTW, in my reading and troubleshooting, I saw something that said I should download the file ExtensionFunctions.php so I pulled this file down from SVN-06-25-2008 ;; > wget http://svn.wikimedia.org /svnroot/mediawiki/trunk/extensions/ExtensionFunctions.php

> mv ExtensionFunctions.php /var/www/htdocs/wiki-svn06252008

This did not resolve my issue at all, still seeing the same problem. ANYONE HAVE ANY IDEAS?
 * If you add wfDebug(print_r($data, true)); in MWSearch_body.php file right after the $data = Http::get( $searchUrl ); line, does that give something useful in your debug log? Or does it give a null? 83.81.5.126 15:35, 29 June 2008 (UTC)
 * Also putting a wfDebug("Raw results [$totalHits]\n"); before $totalHits = intval( $totalHits ); might give useful results 83.81.5.126 15:38, 29 June 2008 (UTC)


 * thanks for the help! so I tried both suggestions, but I obviously don't think I know how to understand the log, but it sure looks like it's put more info in there with your suggestions.


 * First I aded wfDebug(print_r($data, true)); in the extensions/MWSearch/MWSearch_body.php file, right after the $data = Http::get( $searchUrl ); line
 * my debug is now outputting the following upon a search that shows no results in my MediaWiki ;;

 * I am going to try your 2nd suggestion now, again thanks for helping, it really means alot to me! Agentdcooper


 * OK, this is what my debug log shows when I put wfDebug("Raw results [$totalHits]\n"); before $totalHits = intval( $totalHits ); in the extensions/MWSearch/MWSearch_body.php file while leaving your 1st suggestion in = wfDebug(print_r($data, true)); ;

 * I hope that this helps, to me it sounds looks like the "Raw results" are nadda/zero, why would that be? I would love to know how to correct this if possible! any assistance you can provide is more then helpful! --Agentdcooper 01:02, 30 June 2008 (UTC)
 * I definitely think there is something wrong with HTTP::get. More specifically I think MediaWiki is doing something wrong with proxies... Try to disable CURL by replacing if ( function_exists( 'curl_init' ) ) { in includes/HttpFunctions.php with if ( function_exists( 'curl_init' ) && false) {.
 * The problem is probably due to the fact that you are running Lucene on localhost, while Wikimedia uses Lucene on foreign hosts and there might be a bug with HttpFunctions on localhost, but not on port 80. 83.81.5.126 18:09, 30 June 2008 (UTC)


 * Thank you for sticking around to help (whoever u are!) I am thrilled to see you still here to help me!!! I think you are dead-on, I was thinking it might be something with MWSearch extension, but by the sounds of it u are thinking it's an issue with the way MediaWiki uses HTTP:get? I like where yr going, and I am willing to do anything you suggest to try to isolate this, as I really, really want this to work, more than anything!


 * As u suggested, in file /var/www/htdocs/wiki-svn06252008/includes/HttpFunctions.php I changed line 25 FROM ;

if ( function_exists( 'curl_init' ) ) {
 * TO ;

if ( function_exists( 'curl_init' ) && false) {
 * I then saved the updated file (and made a backup of the original), did another update/import of my wiki DB (php maintenance/dumpBackupInit.php --current --quiet > wikidb.xml && java -cp /usr/local/search/ls2/LuceneSearch.jar org.wikimedia.lsearch.importer.Importer -s wikidb.xml svnwikidb  which, BTW, works just fine). From here I went to my wiki main page, and ran a search for a word that is on the Main_Page 3 times, and also is in my XML dump of my wiki DB too, 3 times.... The search came up with this error (again, soo sad) ;

You searched for loopback For more information about searching NOC Information Archive, see Help. No page text matches


 * This is what the Lucene-Search-2 daemon (lsearchd) console scrolled by after running my search ;

 * I left the previous suggestions you gave me yesterday (or the day before?) regarding debug suggestions, so this is what my /var/log/mediawiki/debug_svn_log.txt shows after I ran my search ;

 * So again, I am able to pull up the link listed in the debug file, with the line beginning with "Http::request: GET" = http://localhost:8123/search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10 - this pulls up the following (which sure seems like at least THAT part of Lucene search capabilities is working!);

1 1.0 0 Main_Page


 * I really think you are definately onto something here, I am just not sure where to go next here... any more assistance you can give is much appreciated, I think others may run into this same issue, so who knows maybe you helped identify a bug?! thanks again! --Agentdcooper 19:58, 30 June 2008 (UTC)
 * (the ip was me) Ok this is really strange. From this point I'm very sure that something goes wrong with MediaWiki's HTTP fetching capabilities. I just don't know what. Two more ways to test this (you don't need to reinstall anything or something else):


 * Open a terminal and change the directory to your wiki base: cd /var/www/htdocs/wiki-svn06252008
 * Start a PHP debugging session: php maintenance/eval.php
 * See whether you get something with the following command: $sock = fsockopen('127.0.0.1', 8123); fwrite($sock, "GET /search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10 HTTP/1.0\r\nHost: localhost\r\n\r\n"); print fread($sock, 8192);
 * If that returns proper results, test whether MediaWiki works properly using: print Http::get('http://127.0.0.1:8123/search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10');
 * If that still works try: print Http::get('http://localhost:8123/search/svnwikidb/loopback?namespaces=0&offset=0&limit=20&version=2&iwlimit=10');
 * I hope we get something out that. Bryan 20:52, 30 June 2008 (UTC)

Answer
Hello, I have tried to read through the bunch of information you gave. My Opinion: Your Lucene is running right, because when you "manually" query your Lucene Listener it returns you "MAIN_PAGE". So my advice is that you don't change the conf of your Lucene. I think the problem is inside your Extension MWSearch. Have you tried to run a fresh 1.12 Installation only with the MWSearch Extension to access your existing Lucene Daemon? I think you need nothing more than your MWSearch Extension and no "ExtensionFunctions". Later on I am trying to get more information about your Problem. I am focusing on your MWSearch Extension.... --Bisato 06:24, 30 June 2008 (UTC)
 * Thanks for your suggestion, but unfortunately I have tried that many times in the past when initially troubleshooting I have alot of info posted HERE. Now that page doesn't indicate that I was running 1.12.0, but I can assure you I have tried it many times with just Extension:MWSearch, I get the exact same results I am posting on this page, and the previous page. I have always obtained these results, using MWSearch no matter what OS version I run (on Slackware 11.x thru current stable version 12.1) I have tried this out on multiple Slackware servers, all obtaining the SAME results. I think yr right, I think Lucene-search2 is working properly, just MWSearch is not passing the proper parameters to Mediawiki. I'd love to troubleshoot and fix this, but I just don't know where to go next. Do you have any other suggestions per chance?
 * Thanks to all who've helped! I hope we can get to the bottom of this! peace --Agentdcooper 10:26, 30 June 2008 (UTC)
