Followed this [https://github.com/elasticsearch/elasticsearch](https://github.com/elasticsearch/elasticsearch) guide,
setup elasticSearch and the twitter like information.
As shown below, fuzzy search { "user": "kimc" } can get expected result,
but fuzzy search { "user": "kim" } cannot get results.
What is the cause?
Thank you.

Hi, the reason is that fuzzy queries have a configurable edit distance. The
max distance is 2. The edit distance between "kim" and "kimchy" is 3 (since
3 characters must be inserted). Lucene (the underlying search engine of
elasticsearch / SOLR) cannot efficiently search words with an edit distance
