ElasticSearch: No filter registered for [match]]

Question

I'm trying to do this query to my ElasticSearch Server.

{
    "query" : {
        "match" : {
            "name" : "network"
        }
    },
    "facets" : {
        "departments" : { 
            "terms" : {
                "field" : "department_name"
            } 
        }
    },

    "filter" : {
        "bool": {
            "should": [
                { "match" : {"department_name" : "book"}},
                { "match" : {"department_name" : "electronics"}}]            
        }   
    }
}

Basically, I wish to retrieve all the products that match "network" in its name, but filtering only to those which department_name matches either book or electronics. When I perform this query, I receive this error message.

curl -X POST "http://localhost:9200/products/_search?pretty=true" -d '{
    "query" : {
        "match" : {
            "name" : "network"
        }
    },
    "facets" : {
        "departments" : { 
            "terms" : {
                "field" : "department_name"
            } 
        }
    },

    "filter" : {
        "bool": {
            "should": [
                { "match" : {"department_name" : "book"}},
                { "match" : {"department_name" : "electronics"}}]            
        }   
    }
}

I suppose the key here is QueryParsingException[[products] No filter registered for [match]], but cannot understand what's wrong here.

Answer 1

match is a query, not a filter.

You probably want the term-filter in this case.

Answer 2

Elasticsearch Advanced Filtering

Here's a way you can use match inside of a bool:

{
  "query": {
    "filtered": {
      "query": { //THIS IS THE MAIN SEARCH BLOCK FOR ALL RESULTS
        "match": { 
          "title": { 
            "query": "[MAIN_SEARCH_TERM]", 
            "minimum_should_match": "75%"
          }
        }
      },
      "filter": {
        "bool": {
          "must": [
            {
              "range": { //THIS FILTERS BY DATES GRATER THAN [SOME_DATE]
                "date": {
                  "gte":"[SOME DATE]"
                }
              }
            },
            {
              "geo_distance": { //THIS FILTERS BY GEO POINTS WITHIN [DISTANCE] of [LATITUDE], [LONGITUDE]
                "distance": "[DISTANCE](mi, km)",
                "location": {
                  "lat":"[LATITUDE]",
                  "lon":"[LONGITUDE]"
                }
              }
            }
          ],
          "should": [
            {
              "query": { //THIS FILTERS BY ANOTHER [MATCH_TERM] AND ADDS BOOST TO THAT TERM, YOU CAN USE MULTIPLE OF THESE WITH DIFFERENT [BOOST_INT]
                "match": { 
                  "[PROPERTY]": {
                    "query": "[MATCH_TERM]",
                    "boost": [BOOST_INT]
                  }
                }
              }
            }
          ]
        }
      }
    }
  }
}

Before using geo_point matching and date range filtering, make sure you understand _mapping: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping.html
