Subject [jira] [Commented] (SOLR-3589) Edismax parser does not honor mm parameter if analyzer splits a token
Date Mon, 20 Aug 2012 06:19:38 GMT


Bernd Fehling commented on SOLR-3589:

I would not mix synonyms into this because they need a special seperate treatment.
It might work for "monkeyhouse => monkey house" but what if you have synonyms like "nuclear
fission, kernspaltung, fissione nucleare"?
You would expect to get a search like (nuclear AND fission) OR (kernspaltung) OR (fissione
AND nucleare).
This is a simplified example just to show that if you include synonyms into this issue you
also have to detect/parse/obey the kind of synonym mapping.

> 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.
