[jira] [Commented] (SOLR-9770) Solr should not cache queries that
fail
[ https://issues.apache.org/jira/browse/SOLR-9770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16127553#comment-16127553 ]
Christine Poerschke commented on SOLR-9770:
-------------------------------------------
* http://apache.markmail.org/thread/qiixhqnmqckrfzn4 appears to be the user list thread mentioned in the description.
* In SOLR-11240 [~toke] outlines how the "Too many values for UnInvertedField" exception can be triggered i.e. that could perhaps be used as a starting point for reproducing the autowarming errors here e.g. in a test case perhaps.

> 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: 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.
