Thanks a lot for both of your answers! The QParserPlugin is probably
what I meant, but join queries also look interesting and like the could
maybe solve my use case, too, without any custom code.
However, since this would make it impossible (I think) to have a score
for the results but I do want to do fulltext searches on the returned
field set (with score) it will probably not be enough.
Anyways, I'll look into both of your suggestions. Thanks a lot again!

It depends on your use case. What is you custom criteria how is stored etc.
For example I had two tables, lets say items and permissions tables.
Permissions table was holding itemId,userId pairs. Meaning userId can see this
itemId. My initial effort was index items and add a multivalued field named
WhoCanSeeMe. And fiterQuery on that field using current user.
After sometime indexing become troublesome. Indexing was slowing down. I
switched to two cores for each table and used query time join. (JoinQParser) as
a fq. I didnt have anly plugin for the above.
By the way here is an example of post filter Joel advises :

You're probably want to implement the QParserPlugin as PostFilter.

Hi,
I'm currently looking at writing my first Solr plugin, but I could not
really find any "overview" information about how a Solr request works
internally, what the control flow is and what kind of plugins are available
to customize this at which point. The Solr wiki page on plugins [1], in my
opinion, already assumes too much knowledge and is too terse in its
descriptions.
[1] http://wiki.apache.org/solr/SolrPlugins
If anyone knows of any good ressources to get me started, that would be
awesome!
However, also pretty helpful would be just to know what kind of plugin I
should create for my use case, as I could then at least try to find
information specific to that. What I want to do is filter the search
results (at the time fq filters are applied, so before sorting, facetting,
range selection, etc. takes place) by some custom criterion (passed in the
URL). The plan is to add the data needed for that custom filter as a
separate set of documents to Solr and look them up from the Solr index when
filtering the query. Basically the thing discussed in [2], at 29:07.

So, the question is, what kind of plugin would I use (and how would it
have to be configured)? I first thought it'd have to be a SearchComponent,
but I think with that I'd only get the results after they are sorted and
trimmed to the range, right?
Thanks a lot in advance,
Thomas Seidl
