Using a term query

Searching or filtering for a particular term is very frequent. Term queries work with exact value matches and are generally very fast.

The term queries can be compared to the equal "=" query in the SQL world (for not tokenized fields).

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...

To execute a term query, we will perform the following steps:

1. We execute a term query from the command line:

           curl -XPOST 'http://127.0.0.1:9200/test-index/test-
           type/_search?pretty=true' -d '{
             "query": {
                 "term": {
                     "uuid": "33333"
               ...
