Eduard,
I do not think there is *one* UI for such. Also... I note that it is possible today to
query most of the things you ask below, since the Lucene Query Parser is used.
I believe Savitha's job is to make one such UI (I'm fine with your suggestions,
but please not a super rich and heavy UI!) but, more importantly, a toolset so that UIs
are built.
To get a little hint on "alternative" search engines usages, I'd like to
demo Savitha the inner and technical aspects of the search of Curriki (Solr-based, outside
of XWiki but uses its model, Json integrated, high-performance, closed-source) and
I2geo.net (XWiki-Lucene-based, with strong changes, inside XWiki, partly ontology based,
open-source). Among others, the "advanced search" there is quite different (and
is quite heavy).
I know Savitha and Joshua would be interested to this, who else?
It'd be during next week at some common time.

IMO, XWiki's search feature is severely affected
by the fact that, as a
structured wiki, it does *not* take advantage at all of the fact that the
domain is known (and already mapped in lucene) and, instead, it asks users
for a plain keyword.
If you look at Google, for example, keyword search is perfectly valid,
since the domain is unknown (web pages, free text, etc), but for XWiki, it
is an absolute *must* to provide an advanced search (faceted search)
feature:
- result type
- language
- author
- date
- wiki
- object class
- attachment
- etc.
Only then, IMO, we can really discuss about how we can improve on the
results and tweak the scoring. Just take a look at the search suggest
feature. I, for one, always use search suggest because it is the closest
thing to a "focused" search that reflects my search intent.
Until then, we can only hack solutions that will never be good enough for a
user that wants to find something in XWiki. A magic solution that guesses
what the user is looking for just by entering a single keyword does not
seem to be achievable in the near future (at least not without a brain wave
reader :) ).
On the implementation side, it's actually just a matter of building a
proper UI that generates the lucene query.
Not sure if this helped very much for the topic at hand, but maybe it will
inspire someone reading it :)
Thanks,
Eduard

http://lists.xwiki.org/mailman/listinfo/devs Hi all,
While trying to retrieve the search results had the following doubts.
*Problem: *
*
*
* *Say XWiki has three languages English, Spanish, French. I
give a query in English(some *proper noun*) ,
should it return the documents pertaining only to english or it can
return documents pertaining to other languages too?
If the scenario is such that it retrieves the documents irrespective of
languages, I have few ideas to deal with it.
1) We can get the documents, merge them, add the scores and give it a high
rating. This would help to avoid super
results such as a display of a different match in each language to some
extent.
2) Make it a part of facet search , where search results could be
differentiated base don language.
Would be really helpful to gain your suggestions.
XWiki is pretty unique in the way it handles multilingualism, so I can't
think of an example to follow.
Also, how a multilingual XWiki is going to be used depends a lot on the
particular organization using it, so one generic solution might not make
everybody happy, so multiple solutions to chose from (in the
administration) might be the proper way to go.
Here's how I would like things:
When searching for something, let's say "scorpions", and my current
language is English, I see first documents that are written in English:
"
Search results for "Scorpions":
[100%] Scorpion
[ 95%] The Scorpions
[ 50%] Scorpio
"
After that, we also search for a few top hits in all the other languages
except English, and if we have strong hits (let's say score above 75%), we
display something like:
"
You might be interested in these results in other languages:
[ 98%] [de] The Scoripions
[ 90%] [fr] Scorpiones
[ 89%] [ro] Scorpion
[[Search for "Scorpions" in every language]]
"
Now, I'm not sure when exactly to display this:
- every time when there are hits with a score above a threshold
- only when there are hits with scores higher than the best scoring result
in the current language
- only when there are few results in the current language (less than 5)
