Using the IDS query/filter

The IDs query and filter allow matching documents by their IDs.

Getting ready

You need a working ElasticSearch cluster.

How to do it...

For executing IDS queries/filters, we need to perform the following steps:

1. The ids query for fetching IDs 1, 2, 3 of the test-type type is in the following form:

   curl -XPOST 'http://127.0.0.1:9200/test-index/test-type/_search' -d '{
       "query": {
               "ids" : {
                   "type" : "test-type",
                   "values" : ["1", "2", "3"]
               }
           }
       }
   }'

2. The same query can be converted in a filter query similar to the following one:

   curl -XPOST 'http://127.0.0.1:9200/test-index/test-type/_search' -d '{
       "query": {
           "filtered": {
               "filter": {
                   "ids" : {
                       "type" : "test-type",
                       "values" : ["1", "2", "3"]
                   }
               },
               "query": {
                   "match_all": {}
               }
           }
       }
   }'
