I still have questions about how that's done: Is there a tutorial on how to apply it,
or even a XAR to import a new search page?
Or is that what Petteri is asking for?

I hope xwiki will use the lucene search in future as default search engine!
At least just because of the result score..

I think it's impossible to do the paging properly under the conditions

for a compact and easily customizable search results view, which has
sorting and sort direction functionality. If you want to have it you
should also have my lucene-patches to support sorting directions and to do
AND-searches by default.
If you want I can send these all to you but maybe somebody of the project
team could shortly comment these issues before. If there is a roadmap with
the plugin I could also offer myself to be a contributor. Lucene-plugin
works 100X (well...almost) faster than regular xwiki-searches and is at
least at the moment the only possible choice in my xwiki-environment.
And by the way, many thanks for Ludovic and the whole team for great work!

Petteri

I had the same problem with post-filtering the search results. (there were
not all results displayed, and that caused a problem in a paged view (ex.
just 10 out of 30 on page1, 15 of 30 on page2..)
Maybe you can improve my lucene search page macro?

About the "confusing" results: of course I can do some velocity- or
groovy
-post-processing on the page to filter out the duplicate document names
from results. This is no problem if I want to show the results as one
flat
list but it becomes quite complicated to do efficiently if I want to show
f.ex. 30 hits per page with paging. Basically I mean that all the index
data holded by one page (page content, objects, attachments...) should be
regarded as this page's properties and indexed under one lucenedoc. If I
operationally have understood something incorrectly, please correct me.
What do you think?
-Petteri
I'm testing the version RC1 and have some thoughts about the
Lucene-plugin:
Sorting
-------
At the moment there is no method in the API to choose between the sorting
directions. I think there should be one.
Boolean Queries
---------------
Is the default query-type going to stay an ORed one? Should it better be
an AND-query, like Google? I think most of the surfers expect that
nowadays. At least there could be method to choose between them.
Results
-------
Search results are a bit confusing now. When I search for a word that
appears both in a document, in it's attachment and in it's object's
properties I get three hits. One for each type. There a special cases, of
course, but I think it would be more usable to get in my example case by
default just one hit. There would still remain a method ("type: object")
to distinguish between the types in a query.
If you like, I can provide patches for the two first (minor) issues.
Regards,
Petteri
