[xwiki-devs] Improvement of XWiki search results to include keyword matches (Fine tuning!)
Hi, I spent some time making my XWiki instance show a more useful list of results from the search results, but there is a problem here as the freemarker code is unable to catch a rendering exception (by design of freemarker) on certain searches. If there is an exception, the user is greeted with a long wait, then no results show up at all. This isn't really good enough for my means. My happier solution, would be for the exception to happen and for nothing to be rendered in the preview for this search result. I wondered if there was a better way to achieve my goal than using the rendering mechanisms in the code below. If I can avoid or catch the exception and keep the same functionality that I have now, then I would be in a better position. Code below or on StackOverflow (http://stackoverflow.com/q/17038968/1247302). I'm using XWIKI ENTERPRISE 5.0-MILESTONE-1. I edited the page http://[servername:port]/xwiki/bin/edit/XWiki/Results and then added the code <div class="itemOthers"> #set($outputSyntax = $xwiki.getAvailableRendererSyntax('plain', '1.0')) #if ($outputSyntax) #set ($preview = $xwiki.getDocument($itemfullname).getRenderedContent($outputSyntax)) #set ($regex = $regextool.quote($request.text)) #set ($regex_summarize = "(?i)(?:((\w+)\W+){0,20})\b\w*$regex\w*\b(((\W+)\w+){0,20})") #set ($regex_highlight = "(?i)($regex)") #set ($pattern_summarize = $regextool.compile($regex_summarize)) #set ($matcher_summarize = $pattern_summarize.matcher($preview)) #foreach ( $match_loop in [0,1,2,3,4,5,6,7,8,9] ) #if ($matcher_summarize.find()) #if ($match_loop > 0) <strong> | </strong> #end $escapetool.html($matcher_summarize.group(0)).replaceAll($regex_highlight,'<span style="background-color:yellow;">$1</span>') #end #end #end </div> Thanks, Stuart Disclaimer: The contents of this E-mail plus any attachment is intended for the use of the addressee only and is confidential, proprietary and may be privileged.

Hi Stuart, Starting with XWiki 5.1 the default search engine is based on Apache Solr and the search UI has been redesigned. The page you mentioned, XWiki.Results, is used by Lucene and Database search but not by Solr search. Since we're focusing on Solr, I advise you to upgrade and to check if you have the same problem when using Solr. Hope this helps, Marius On Mon, Nov 18, 2013 at 6:37 PM, Stuart Stephen <[email protected]> wrote:

Thanks for coming back to me on this Marius. I will look into upgrading XWiki to a newer release.
