Elasticsearch exact matches on analyzed fields

Question

Is there a way to have ElasticSearch identify exact matches on analyzed fields? Ideally, I would like to lowercase, tokenize, stem and perhaps even phoneticize my docs, then

Answer 1

You can keep the analyzer as what you expected (lowercase, tokenize, stem, ...), and use query_string as the main query, match_phrase as the boosting query to search. Something like this:

{
   "bool" : {
      "should" : [
         {
            "query_string" : {
               "default_field" : "your_field",
               "default_operator" : "OR",
               "phrase_slop" : 1,
               "query" : "Hamburger"
            }
         },
         {
            "match_phrase": {
               "your_field": {
                  "query": "Hamburger"
               }
            }
         }
      ]
   }
}

It will match both documents, and exact match (match_phrase) will be on top since the query match both should clauses (and get higher score)

default_operator is set to OR, it will help the query "Hamburger Buns" (match hamburger OR bun) match the document "Hamburger" also. phrase_slop is set to 1 to match terms with distance = 1 only, e.g. search for Hamburger Buns will not match document Hamburger Big Buns. You can adjust this depend on your requirements.
