Prioritize Exact/Like Matches


(RobBob) #1

Hello,

I have a list of a few thousand categories and I am having trouble prioritizing exact/like matches to the top. For example, I will search for "Movie Theater" and be returned a list of items from my index in this order:

Performing Arts Theater
Dinner Theater
Movie Studio
...
Movie Theater

How can I have the exact result returned first and why isn't it happening already?

curl -XPUT http://localhost:9200/categories -d '{
  "settings": {
    "analysis": {
      "filter": {
        "category_synonym_filter": {
          "type": "synonym",
          "synonyms": ["bike,bicycle", "bar,pub"]
        }
      },
      "analyzer": {
        "lower_synonyms": {
          "tokenizer": "standard",
          "filter": ["lowercase", "category_synonym_filter"]
        }
      }
    }
  }
}'

curl -XPUT http://localhost:9200/categories/category/_mapping -d '{
  "category" : {
    "properties" : {
      "category_description" : {
        "type" : "string",
        "analyzer": "lower_synonyms"
      },
      "type" : {
        "type" : "string",
        "index" : "not_analyzed"
      }
    }
  }
}'

{size=100, query={bool={filter={bool={must=[{query_string={query=movie theater* OR movie theater OR movie theater~1, fields=[category_description]}}]}}, must={match_all={}}}}, from=0}

Thank you in advance!
