[jira] [Comment Edited] (SOLR-18175) A FieldExistsQuery IllegalStateException should result in HTTP 400 not 500 error
[ https://issues.apache.org/jira/browse/SOLR-18175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18071866#comment-18071866 ]

-------------------------------------------------------------------
The exception is created or thrown from lucene's code. In SolrQueryParserBase it starts with the parsing but i assume this should cause at rewrite so rewrite is at lucene level.
throw new IllegalStateException(buildErrorMsg(fieldInfo));
[~dsmiley] Can you confirm if this change we need to handle in solr?

> If you issue an existence query {{field:*}} yet that field does not support Lucene's {{FieldExistsQuery}}, FEQ.rewrite will throw IllegalStateException:
> bq. FieldExistsQuery requires that the field indexes doc values, norms or vectors, but field 'foo' exists and indexes neither of these data structures
> Solr ultimately returns a HTTP 500, which is not what we want. We want HTTP 400. Note that I discovered this via a {{facet.query}} and have yet to check if it were to happen simply in a {{q}}. The change likely involves modifying Solr {{FieldType.getExistenceQuery}} to throw an exception with the 400 code.
