Erick Erickson created SOLR-9770:
------------------------------------

             Summary: Solr should not cache queries that fail
                 Key: SOLR-9770
                 URL: https://issues.apache.org/jira/browse/SOLR-9770
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: trunk, 6.4
            Reporter: Erick Erickson
            Priority: Minor


Bram Van Dam on the user's list had a problem with a bad query causing an exception:

java.lang.IllegalStateException: Too many values for UnInvertedField
faceting on field text. 

Then the query apparently got into one of the caches and was then autowarmed leading to the error every time a new searcher was opened.

This does _not_ happen with, say, a query that references an undefined field. Such a query doesn't get into the cache in the first place.

I have not been able to verified this but it seems worth a JIRA to investigate at least, no query that throws an exception should get into the caches. You can imagine a situation where this leads to OOM errors and Solr needing to be restarted to get past it.
