Using a match query

Elasticsearch provides a helper to build complex span queries that depend on simple preconfigured settings. This helper is called match query.

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 match queries, we will perform the following steps:

1. The standard usage of a match query simply requires the field name and the query text. Consider the following example:

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