Subject [jira] Updated: (JSPWIKI-498) Performance Issues with Lucene Index
Date Tue, 10 Feb 2009 16:59:00 GMT


Kurt Stein updated JSPWIKI-498:

    Attachment: patch_lucene_search.txt

OK, I have finished my work. 

This one fixes the search dilemma for LuceneSearchProvider described above.

Additionally it shows all pages for a query. But it shows secret content(user without pagepermission)
only to authorized users.

Reason: We often have users saying: This is not in the wiki. But it is in the wiki, they are
just not authorized.(We still need a little bit of internalization for this piece of code).

This way, they see there is a page an so they can ask the admin for access to this page. 

As soon as they changes are accomplished I will provide my search template. But i donĀ“t want
to mix to much code for you at one time.

PS: There is a dependency in LuceneSearchProvider for PDBox because I am actually indexing
my pdf files ;-) I think this is a good part to get pdf indexed so I commit this too.

> Our Wiki-Luceneindex has swollen to 33 MB and if someone searches words like "find" he
gets about 500 results. Only problem is, it takes about 30 seconds to complete the search.
> I have looked a bit into the problem and there is something strange to me. JSPWiki searches
twice every query. 
> Once in search.jsp and afterwards in AjaxSearch.jsp.
> The filteredList from search.jsp is written to the pagecontext but this information is
never read within the AjaxSearch.jsp. Thus AjaxSearch.jsp makes a second search.
