remove fuzzy factor from mapping (internally implemented) 

we want to support ~ notion in query parser for types other than strings, we are getting there, one can do now age:10~5, we would love to support it for dates, as in timestamp:2012-10-10~5d, but that requires changes in the query parser to support strings after the ~ sign

* We override this one so we can get the fuzzy part to be treated as string, so people can do: "age:10~5". Note,
* we would love to support also "timestamp:2012-10-10~5d", but sadly the parser expects only numbers after the ~,
* hopefully we can change that in Lucene.
