Thomas Egense commented on SOLR-6376: ------------------------------------- Vitaliy Zhovtyuk: What did you do different to trigger the bug in a unittest environment this time? > Edismax field alias bug > ----------------------- > > Key: SOLR-6376 > URL: https://issues.apache.org/jira/browse/SOLR-6376 > Project: Solr > Issue Type: Bug > Components: query parsers > Affects Versions: 4.6.1, 4.7, 4.7.2, 4.8, 4.9, 4.10.1 > Reporter: Thomas Egense > Priority: Minor > Labels: difficulty-easy, edismax, impact-low > Attachments: SOLR-6376.patch, SOLR-6376.patch > > > If you create a field alias that maps to a nonexistent field, the query will > be parsed to utter garbage. > The bug can reproduced very easily. Add the following line to the /browse > request handler in the tutorial example solrconfig.xml > <str name="f.name_features.qf">name features XXX</str> > (XXX is a nonexistent field) > This simple query will actually work correctly: > name_features:video > and it will be parsed to (features:video | name:video) and return 3 results. > It has simply discarded the nonexistent field and the result set is correct. > However if you change the query to: > name_features:video AND name_features:video > you will now get 0 result and the query is parsed to > +(((features:video | name:video) (id:AND^10.0 | author:and^2.0 | > title:and^10.0 | cat:AND^1.4 | text:and^0.5 | keywords:and^5.0 | manu:and^1.1 > | description:and^5.0 | resourcename:and | name:and^1.2 | features:and) > (features:video | name:video))~3) > Notice the AND operator is now used a term! The parsed query can turn out > even worse and produce query parts such as: > title:2~2 > title:and^2.0^10.0 > Prefered solution: During start up, shut down Solr if there is a nonexistant > field alias. Just as is the case if the cycle-detection detects a cycle: > Acceptable solution: Ignore the nonexistant field totally. > Thomas Egense -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
