Does the following query has any performance impact over

Hi,
Is it possible to constrain a resultset using a filter query to only
return the top 100 documents for a particular field?
Say I have a field called 'hits' that has the total number of hits for
that item. I want to return only the documents that have the top 100
highest hits.

It's probably not exactly what you're looking for, but you can do

Solr's caches should be transparent - they should only speed up
queries, not change the result of queries.

I ll be thankful upon getting an elaboration.
I appear to be getting only a small number of items imported into Solr
when doing a full-import against an oracle data-provider. The query I'm
running is something approximately similar to:
SELECT ID, dbms_lob.substr(Text, 4000, 1) Text, Date,
LastModified, Type, Created, Available, Parent, Title

When you delete document, and then COMMIT your changes, new caches will be
warmed up (and prepopulated by some key-value pairs from old instances),
etc:

To do any serious Solr debugging (or filter development) you also need the
Solr source code tree. And you'd like them to be in sync, so that the
Lucene code you see is exactly the same as what was used for the Solr
version you're working with.

Hi all,
If I have a set of filter queries that I'd like to apply but nothing
that I particularly would like to put into the :q parameter (since I'd
like all of the scopes to be cached), is there any problem with just
passing [* TO *] for the :q param? Any performance implications?
Thanks!

Thanks, Shalin. The *:* sounds good - so that'll definitely have no
effect on query performance?
What I meant was, I'd like all of the queries that I'm using to
restrict search results to be cached (as filter queries are) - which
is why I don't have anything I'd particularly like to put into the

All query results are added to the query result cache so any cost is
one-time only (until a commit happens or eviction happens).
Hey Shalin,
Thanks for the help. The particular attraction of filter queries is
that they are cached separately, and our application takes advantage
of that fact, since we often employ several filters in one search -
while the combinations of filters are numerous, the individual filters

What version of Solr are you using?
Solr1.3 and Lucene 2.4 defaulted to an index reader implementation

First of all , thanks a lot for the clarification.Is there any way to see,
how this cache is working internally and what are the objects being stored
and how much memory its consuming,so that we can get a clear picture in
mind.And how to test the performance through cache.
