[jira] [Commented] (SOLR-1982) Leading wildcard queries work for
"all" fields if ReversedWildcardFilterFactory is used for "any" field
[ https://issues.apache.org/jira/browse/SOLR-1982?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13157350#comment-13157350 ]
Yonik Seeley commented on SOLR-1982:
------------------------------------
I ran onto this myself while looking at the query parser code again. We introspect all of the schema field types every time a query parser is created - really not ideal for performance. Perhaps this should be cached in the schema, or at
Zero length prefix queries have pretty much always been allowed in solr, and leading wildcard queries have been effectively allowed with the default example schema since '09. Seems like when we get around to fixing this stuff, permissive should be the default, but should somehow be overridable (or maybe we can punt to a higher level parser like edismax to handle per-field overrides).

> Project: Solr
> Issue Type: Bug
> Affects Versions: 1.4, 1.4.1
> Reporter: Hoss Man

> As noted on the mailing list...
> http://search.lucidimagination.com/search/document/8064e6877f49e4c4/leading_wildcard_query_strangeness
> ...SolrQueryParse supports leading wild card queries for *any* field as long as at least one field type exists in the schema.xml which uses ReversedWildcardFilterFactory -- even if that field type is never used.
> This is extremely confusing, and ost likely indicates a bug in how SolrQueryParser deals with ReversedWildcardFilterFactory
