Description

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.
