Jim Ferenczi commented on LUCENE-7799: -------------------------------------- There is an option called {{autoGenerateMultiTermSynonymsPhraseQuery}} which when activated builds phrase query for multi-terms synonyms. The naming is a bit misleading but it can achieve what you're describing. The idea, which should maybe be extended, is to build a phrase query when side paths of different length are encountered inside the query. With a WordDelimiterGraphFilter that preserves original tokens ({{preserveOriginal}}) this heuristic works perfectly since each split creates side paths of different length. > Classic query parser should allow autoGeneratePhraseQueries=true when > splitOnWhitespace=false > --------------------------------------------------------------------------------------------- > > Key: LUCENE-7799 > URL: https://issues.apache.org/jira/browse/LUCENE-7799 > Project: Lucene - Core > Issue Type: Bug > Components: core/queryparser > Reporter: Steve Rowe > > LUCENE-7533 disabled the option combination > {{splitOnWhitespace=false}}/{{autoGeneratePhraseQueries=true}} because of how > {{autoGeneratePhraseQueries=true}} is handled: a query chunk is treated as if > it were literally quoted. When {{splitOnWhitespace=false}}, a query chunk > can be multiple whitespace-separated words, and auto-quoting multiple terms > will produce inappropriate phrase queries. > I have an idea about how to fix this: {{autoGeneratePhraseQueries=true}} is > supposed to cause phrase queries to be constructed when multiple analyzed > terms result from a single query word, e.g. when WordDelimiter(Graph)Filter > splits words up. Maybe this could be re-implemented in terms of offsets, > since all terms from the same original term share the same offsets. -- 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
