The original synonyms filter with > default {{expand=true}} produces the following map when parsing a line: > Input: > {noformat} > a, b, c > {noformat} > Becomes: > {noformat} > a => a, b, c > b => a, b, c > c => a, b, c > {noformat} > But the managed filter excludes the original term in the mapping, so an input > {{\["a", "b", "c"\]}} becomes: > {noformat} > a => b, c > b => a, c > c => a, b > {noformat} > This can also be seen in {{TestManagedSynonymFilterFactory.java}} where it is > tested explicitly, while the tests for the file based synonymfilter expect an > all-way expand including the original term. > This causes a query for "a" to *not* match documents with the term "a", but > only those with term "b" or "c". > The offending line in {{ManagedSynonymFilterFactory}} is this > {code} > 188: treeTerms.remove(origTerm); > {code} -- 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
