[jira] [Commented] (SOLR-9752) Reliable test failure in
TestFieldCacheSort (Solr copy)
[ https://issues.apache.org/jira/browse/SOLR-9752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15657484#comment-15657484 ]
Yonik Seeley commented on SOLR-9752:
------------------------------------
Hopefully this is just a test bug and not a Lucene bug, but I don't see anything wrong with the test on first glance.
The test itself also has nothing to do with the fieldCache - it's testing sorting by score.
Maybe it's something to do with this?
{code}
sim=RandomSimilarity(queryNorm=false,coord=crazy):
{code>
Perhaps some sort of crazy scoring can lead the scores of the two matching documents to be equal, and hence a sort by score won't yield the reverse order of a sort by reverse score (that's what the test is testing).
So perhaps this is just a little bit too much random craziness in the test framework that makes this particular test not always true.
