* Display results of pagename search.

* 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 1.28 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
// End:
