[xwiki-users] Lucene Searching with "object:" keyword does not show expected results

Hi, With XE 2.2.1, I think I have some issues retrieving expected results from Lucene search, using "object:" term. For example, if I want to search for comments containing "test", I would enter as search term in Main.LuceneSearch: test AND object:XWiki.XWikiComments This returns no result in my case. But then if I use Luke to browse the Lucene index in $TOMCAT_HOME/work/Catalina/localhost/xwiki/lucene, I can find at least 5 documents for which field "XWiki.XWikiComments.comment" matches with "test". I believe that Main.LuceneSearch should return exactly the same result, and not an empty set ? Another use-case, if my search term is only "object:XWiki.XWikiComments", page retrieves only 2 results. There are far more comments in my wiki of course ... Am I missing something ? Best regards, Jeremie
