-----------------------------------
Summary: ManagedSynonymFilterFactory does not parse multi-term
synonyms
Key: SOLR-10264
URL: https://issues.apache.org/jira/browse/SOLR-10264
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Schema and Analysis
Affects Versions: 6.4.2
Reporter: Jörg Rathlev
Priority: Minor
The parser that the {{ManagedSynonymFilterFactory}} uses to parse the JSON
resource into a synonym map does not parse multi-term synonyms in the expected
way.
If the synonym {"foo bar":"baz"} is added to the managed resource, the expected
behavior is that the multi-term synonym "foo bar" will be mapped to the synonym
"baz".
In the {{analyze}} method of {{SynonymMap.Parser}}, multiple origin terms are
concatenated with a separating {{SynonymMap.WORD_SEPARATOR}}, but the
{{analyze}} method is not used by the parser in the
{{ManagedSynonymFilterFactory}}.
As a workaround, multi-term synonyms can be uploaded separated by a null
character, i.e., uploading {"foo\u0000bar":"baz"} works.
