Subject [jira] [Updated] (SOLR-3589) Edismax parser does not honor mm parameter if analyzer splits a token
Date Thu, 01 Nov 2012 05:07:16 GMT


Robert Muir updated SOLR-3589:

    Attachment: SOLR-3589.patch

More tests: I think this patch is ready actually.

Its well contained, we only apply this when the analyzer splits a token (e.g. CJK), not to
any structured queries and not for the synonyms case.

> With edismax mm set to 100%  if one of the tokens is split into two tokens by the analyzer
chain (i.e. "fire-fly"  => fire fly), the mm parameter is ignored and the equivalent of
 OR query for "fire OR fly" is produced.

words such as Chinese or Japenese.
