Michael McCandless commented on LUCENE-7698: -------------------------------------------- Hmm, no good, sorry about this ... thank you for reporting this [~emaijala]; I'll try to make a Lucene test case showing this. > CommonGramsQueryFilter in the query analyzer chain breaks phrase queries > ------------------------------------------------------------------------ > > Key: LUCENE-7698 > URL: https://issues.apache.org/jira/browse/LUCENE-7698 > Project: Lucene - Core > Issue Type: Bug > Components: core/queryparser > Affects Versions: 6.4, 6.4.1 > Reporter: Ere Maijala > Labels: regression > > (Please pardon me if the project or component are wrong!) > CommonGramsQueryFilter breaks phrase queries. The behavior also seems to > change with addition or removal of adjacent terms. > Steps to reproduce: > 1.) Download and extract Solr (in my test case version 6.4.1) somewhere. > 2.) Modify > server/solr/configsets/sample_techproducts_configs/conf/managed-schema and > modify text_general fieldType by adding CommonGrams(Query)Filter before > stopWordFilter: > <fieldType name="text_general" class="solr.TextField" > positionIncrementGap="100"> > <analyzer type="index"> > <tokenizer class="solr.StandardTokenizerFactory"/> > <filter class="solr.CommonGramsFilterFactory" ignoreCase="true" > words="stopwords.txt" /> > <filter class="solr.StopFilterFactory" ignoreCase="true" > words="stopwords.txt" /> > <!-- in this example, we will only use synonyms at query time > <filter class="solr.SynonymFilterFactory" > synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/> > --> > <filter class="solr.LowerCaseFilterFactory"/> > </analyzer> > <analyzer type="query"> > <tokenizer class="solr.StandardTokenizerFactory"/> > <filter class="solr.CommonGramsQueryFilterFactory" ignoreCase="true" > words="stopwords.txt"/> > <filter class="solr.StopFilterFactory" ignoreCase="true" > words="stopwords.txt" /> > <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" > ignoreCase="true" expand="true"/> > <filter class="solr.LowerCaseFilterFactory"/> > </analyzer> > </fieldType> > 3.) Add "with" to > server/solr/configsets/sample_techproducts_configs/conf/stopwords.txt and > make sure the file has correct line endings (extracted from Solr zip it seems > to contain DOS/Windows lien endings which may break things). > 4.) Run the techproducts example with "bin/solr -e techproducts" > 5.) Browse to > <http://localhost:8983/solr/techproducts/select?q=%22iPod%20with%20Video%22&debugQuery=true> > 6.) Observe that parsedquery in the debug output is empty > 7.) Browse to > <http://localhost:8983/solr/techproducts/select?q=%22Apple%2060%20GB%20iPod%20with%20Video%20Playback%20Black%22&debugQuery=true> > 8.) Observe that parsedquery contains ipod_with as expected but not > with_video. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
