{!cache=false} for regular queries?
Hi,
We have the ability to turn off caching for filter queries -
http://wiki.apache.org/solr/CommonQueryParameters#Caching_of_filters
I didn't try it, but I think one can't turn off caching for regular
queries, a la:
q={!cache=false}<query here>
Is there a reason this could not be done?
Thanks,
Otis

Mikhail:
Interesting point! Thanks! I haven't looked at the implementation enough to
know, but it looks like these are unrelated? You'd have to happen to have a
fq clause you'd already submitted (and cached) for this to happen?
But like I said, I don't know the code. I didn't realize this even happened
BTW, so I'm glad you pointed it out!

Eric,
it's worth to mention that queries which sorts by field can potentially
blows filter cache
http://wiki.apache.org/solr/SolrCaching#useFilterForSortedQuery here is the
hint might work out.

But I don't know whether it's worth worrying about. queryResultCache is
pretty small.
I think of it as a map where the key is the text of the query and the value
is an
int[queryWindowSize]. So bypassing the cache is probably not going to make
much
difference.
YMMV of course.
Best

It should bypass cache for sure
https://github.com/apache/lucene-solr/blob/34a92d090ac4ff5c8382e1439827d678265ede0d/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java#L1263
