Matt Weber commented on LUCENE-7824: ------------------------------------ Sure, looks good then! > Multi-word synonyms rule with common terms at the same position are buggy > ------------------------------------------------------------------------- > > Key: LUCENE-7824 > URL: https://issues.apache.org/jira/browse/LUCENE-7824 > Project: Lucene - Core > Issue Type: Bug > Reporter: Jim Ferenczi > Attachments: LUCENE-7824.patch > > > The automaton built from the graph token stream tries to pack common terms in > multi word synonyms that appear at the same position. This means that some > states inside a multi word synonym can have multiple transitions. > As a result the intersection point of the graph are not computed correctly. > For example the synonym rule: "ny, new york city, new york" is not applied > correctly to the query "ny police". > In this case "police" is detected as part of the multi synonyms path and we > create the disjunction between: > "ny police", "new york police", ... > I pushed a patch that removes this optim (and creates a single transition > from each state) in order to ensure that the intersection points of the graph > always showed up at the end of the multi synonym paths. > [~mattweber] can you take a look ? -- 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
