Hello we are using SOLR 6.6. we recently noticed unusual CPU spike. while one of customer did search with ** in query string.
we had customer who searched for following term q = N*W* 154 ** underpass it caused CPU to go above 80%. our normal range of CPU is around 20%. I wanted to know few things. 1. what does ** mean in SOLR search. 2. Is there a bug filed already for this issue. Please let me know if you need more information. Thanks Shreyas Kothiya
