/**
 * Display results of pagename search. 
 * Provides no own input box, just <?plugin-form TitleSearch ?> is enough.
 * Fancier Inputforms can be made using WikiForm Rich, to support regex and case_exact args.
 *
 * If only one pages is found and auto_redirect is true, this page is displayed immediatly, 
 * otherwise the found pagelist is displayed.
 * The workhorse TextSearchQuery converts the query string from google-style words 
 * to the required DB backend expression.
 *   (word and word) OR word, -word, "two words"
 * regex=auto tries to detect simple glob-style wildcards and expressions, 
 * like xx*, *xx, ^xx, xx$, ^word$.

// $Log: TitleSearch.php,v $
// Revision 1.29  2007/01/02 13:23:30  rurban
// note to deprecate livesearch hack
//
// Revision 1.28  2005/09/10 21:33:08  rurban
// support enhanced API
//
// Revision 1.27  2005/02/03 05:09:57  rurban
// livesearch.js support
//
// Revision 1.26  2004/11/27 14:39:05  rurban
// simpified regex search architecture:
//   no db specific node methods anymore,
//   new sql() method for each node
//   parallel to regexp() (which returns pcre)
//   regex types bitmasked (op's not yet)
// new regex=sql
// clarified WikiDB::quote() backend methods:
//   ->quote() adds surrounsing quotes
//   ->qstr() (new method) assumes strings and adds no quotes! (in contrast to ADODB)
//   pear and adodb have now unified quote methods for all generic queries.
//
// Revision 1.25  2004/11/26 18:39:02  rurban
// new regex search parser and SQL backends (90% complete, glob and pcre backends missing)
//
// Revision 1.24  2004/11/25 08:30:58  rurban
// dont extract args
//
// Revision 1.23  2004/11/23 15:17:19  rurban
// better support for case_exact search (not caseexact for consistency),
// plugin args simplification:
//   handle and explode exclude and pages argument in WikiPlugin::getArgs
//     and exclude in advance (at the sql level if possible)
//   handle sortby and limit from request override in WikiPlugin::getArgs
// ListSubpages: renamed pages to maxpages
//
// Revision 1.22  2004/11/23 13:35:49  rurban
// add case_exact search
//
// Revision 1.21  2004/02/17 12:11:36  rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.20  2003/11/02 20:42:35  carstenklapp
// Allow for easy page creation when search returns no matches.
// Based on cuthbertcat's patch, SF#655090 2002-12-17.
//
// Revision 1.19  2003/03/07 02:50:16  dairiki
// Fixes for new javascript redirect.
//
// Revision 1.18  2003/02/21 04:16:51  dairiki
// Don't NORETURN from redirect.
//
// Revision 1.17  2003/01/18 22:08:01  carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//

// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
// indent-tabs-mode: nil
