When XWiki search results come back, there is no indication on the context of the match. Only a title and a few when and who items returned. Is there a way of improving the results to include a content summary highlighting the matches found?
Yes, certainly for standard keyword based searches, this velocity code should do the trick. It was developed on XWiki Enterprise 5.0 Milestone 1.
Edit the page: http://[servername:port]/xwiki/bin/edit/XWiki/Results
I added my changes below the "rating" section, but you can play with the layout to suit your needs.
Add the following code which will display up-to 10 keyword matches and the 20 preceding and succeeding words around the keyword. Each match string will be separated by the pipe symbol '|' and the keywords are then highlighted in yellow.
Obviously it would be nice to make this match a skin colour, but for my purposes I am not interested in that level of development.
<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>
