Subject Re: Proximity searching in percentage
Date Thu, 07 May 2015 12:00:10 GMT
Hi !
Currently Solr builds FST to provide proper fuzzy search or spellcheck
suggestions based on the string distance .
The current default algorithm is the Levenstein distance ( that returns the
number of edit as distance metric).
In your case you should calculate client side, the edit you want to apply
to your search.
In your client code, should be not difficult to process the query and apply
the proper number of edit depending on the length.

Anyway the max edit for the levenstein default distance is fixed to 2 .
