prefix fuzzy query (not using query_string)

Question

I want to do prefix fuzzy search on single term. Basically I want to get same result as if this search request has been sent:

{
  "from": 0,
  "size": 100,
  "query": {
    "query_string": {
      "query": "dala~*"
    }
  },
  "filter": {}
}

but without query_string syntax parsing. Search above should match to Dallas term.

"dala~*" query string definitely works for me and Elastc Search documentation states that internal query string is parsed into combination of simplier query conditions. So I am looking if someone can shed some light to which combination of queries it will be parsed. — Vitaliy Kalinin, Mar 07 '13 at 15:31
After further testing it looks like this query "dala~*" doesn't work as expected, i.e. it splits it on 2 parts "dala~" and "*". And due to last term all documents are matched. But I am still intersted if it is possible to get both partial and fuzzy matching. — Vitaliy Kalinin, Mar 07 '13 at 17:51

In ElasticSearch, if you set fuzzy_prefix_length, you should be able to specify just the fuzzy tilde and get prefix matching:

{
  "from": 0,
  "size": 100,
  "query": {
    "query_string": {
      "query": "dala~",
      "fuzzy_prefix_length": 3
    }
  },
  "filter": {}
}
