Subject [jira] Commented: (SOLR-572) Spell Checker as a Search Component
Date Wed, 21 May 2008 04:10:55 GMT


Shalin Shekhar Mangar commented on SOLR-572:

Oleg -- Thanks for trying out the patch. No, currently it does not signal if suggestions are
not found, it just returns the query terms themselves. I'll add that feature.

> * Allow creating a spell index on a given field and make it possible to have multiple
spell indices -- one for each field
> * Give suggestions on a per-field basis
> * Given a multi-word query, give only one consistent suggestion
> * Process the query with the same analyzer specified for the source field and process
each token separately

> Consistency criteria for a multi-word query can consist of the following:
> * Preserve the correct words in the original query as it is
> * Never give duplicate words in a suggestion
