Mike Klaas commented on SOLR-407:
---------------------------------
Good catch! This can be fixed in standard request handler as follows:
if(null != ncFilters) {
BooleanQuery target;
if(query instanceof BooleanQuery) {
target = (BooleanQuery)query;
} else {
target = new BooleanQuery(true);
target.add(query, BooleanClause.Occur.MUST);
}
U.addFilters(ncFilters, target);
query = target;
}
DisMax I don't think is a problem since it is adding to the top-level boolean
query (can the dismax parser produce pure negative queries anyway?)
I've fixed this with a test in my local copy. If we pursue this any further,
I'll post a patch (also incorporating Yonik's localParams suggestion).

> Key: SOLR-407
> URL: https://issues.apache.org/jira/browse/SOLR-407
> Project: Solr
> Issue Type: New Feature
> Components: search
> Affects Versions: 1.3
> Reporter: Mike Klaas
> Assignee: Mike Klaas
> Priority: Minor
> Fix For: 1.3
>
> Attachments: fq.nocache.patch
>
>
> Add a fq.nocache parameter (that may be specified multiple times) that adds
> filter clauses to the query which are not cached. Further, these filters are
> embedded directly into the BooleanQuery, which should be more efficient when
> filters are not reused.
