Hi,

what is the difference between mlt and flt queries?

[http://www.elasticsearch.com/docs/elasticsearch/rest\_api/query\_dsl/more\_like\_this\_query/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/query_dsl/more_like_this_query/)  
[http://www.elasticsearch.com/docs/elasticsearch/rest\_api/query\_dsl/fuzzy\_like\_this\_query/](http://www.elasticsearch.com/docs/elasticsearch/rest_api/query_dsl/fuzzy_like_this_query/)

Regards,  
Lukas

In short, fuzzy\_like\_this is similar to more\_like\_this, just adds  
"fuzziness" to the terms extracted from the source text when building the  
"like this" query.
