Hi Michael/Jens,
Thanks for your contribution Michael.
1) I didn't know Jens had a page documenting the Lucene plugin. The
page is quite nice and much better than ours at http://www.xwiki.org/
xwiki/bin/view/Code/LucenePlugin.
Jens, would you mind if we merge the content of your page in the one
at xwiki.org? Also, my understanding is that you donated the Lucene
plugin to the XWiki project some time back. Is that correct? If so
maybe we could deprecate your lucene doc page (once and if you agree
to merge the content with the one on xwiki.org). WDYT?
2) Michael, In Velocity, looping is done with foreach. That's the
only loop there is I think.
3) Michael, what would be nice would be if you could add your code as
a Code Snippet on xwiki.org: http://www.xwiki.org/xwiki/bin/view/Code/
Snippets (there's a "Add snippet" on the right). In that manner we'll
be able to add a link to it from the Lucene plugin. It would be nice
if you could put a screenshot of the result on the Code Snippet page
so that users can see how it looks and decide if they want to use
your snippet. WDYT?
Thanks a lot

With RC1 lucene seems to work again, so i have costumized the
existing search
form from jkraemer
(http://www.jkraemer.net/static/maven/xwiki/plugins/lucene-plugin/
install.html)
But keep attention: it's just a quick&dirty example to display the
results
in a table ;-)
As im not very familiar with velocity, the code is quite ugly! (for
example
i didn't find a while loop to output the number of stars for score-
quality,
so i did it with if, if, if..)
it still has some bugs:
* if you search for a regular expression (e.g. win*), then the
query for the
next page will be win</strong>
* non wiki-documents and non-attachments will be hidden from the
results, so
it could happen that you see an empty page with a link to the next
results
(that's because searchresults.hitcount returns all results, also
the hidden
ones..)
* many more..
* icons are hard-coded.. (/skins/lgs/*.png)
You can get the icons for free from famfamfam:
