Hi, today we updated solr to version 9.1 (lucene version 9.3) Since then we noticed plenty of TooManyNestedClauses in the logs. Our setting for maxClauseCount is 1024 I played around a lot and could trace it down to this:
* I built an index from scratch with two fields (id is unique key) and luceneMatchVersion 9.3: <field name="id" type="string_dv" indexed="true" stored="true" multiValued="false" required="true"/> <field name="createdById" type="p_long_dv" indexed="true" stored="false" multiValued="false" /> <fieldType name="string_dv" class="solr.StrField" sortMissingLast="true" omitNorms="true" docValues="true" /> fieldType name="p_long_dv" class="solr.LongPointField" docValues="true" omitNorms="true" /> As expected this works (the dots(...) represent the complete set of numbers up to 1024): curl -XGET http://localhost:8983/solr/myindex/select?q=+id:(1 2 3 ... 1024) And this fails: curl -XGET http://localhost:8983/solr/myindex/select?q=+id:(1 2 3 ... 1025) But when I use the other field (categoryId) this fails: curl -XGET http://localhost:8983/solr/myindex/select?q=+categoryId:(1 2 3 ... 1024) It works until 512 and starts failing from 513 clauses No difference when doing it like this: curl -XGET http://localhost:8983/solr/myindex/select?q=+(categoryId:1 categoryId:2 ... categoryId:1024) Am I misunderstanding the limit maxClauseCount? I'm pretty sure that we did not have any issues with this before. Thanks, Michael
