Using IDs query

The ID's query and filter allows matching documents by their IDs.

Getting ready

You need an up-and-running Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe in Chapter 2, Downloading and Setup.

To execute curl via the command line, you need to install curl for your operative system.

To correctly execute the following commands, you need an index populated with the chapter_05/populate_query.sh script available in the online code.

How to do it...

For executing the ID's queries/filters, we will perform the step given as follows:

1. The IDs query for fetching IDs "1", "2", "3" of type test-type is in this form:

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