+description: Learn how to use the Redis query engine with JSON
+linkTitle: JSON query example
+title: Example - Index and query JSON documents
+weight: 2
+---
+
+This example shows how to create a
+[search index]({{< relref "/develop/interact/search-and-query/indexing" >}})
+for [JSON]({{< relref "/develop/data-types/json" >}}) data and
+run queries against the index.
+
+Make sure that you have Redis Stack and `Jedis` installed. 
+
+Start by importing dependencies:
+
+{{< clients-example java_home_json import >}}
+{{< /clients-example >}}
+
+Connect to the database:
+
+{{< clients-example java_home_json connect >}}
+{{< /clients-example >}}
+
+Create some test data to add to the database:
+
+{{< clients-example java_home_json create_data >}}
+{{< /clients-example >}}
+
+Create an index. In this example, only JSON documents with the key prefix `user:` are indexed. For more information, see [Query syntax]({{< relref "/develop/interact/search-and-query/query/" >}}).
+
+{{< clients-example java_home_json make_index >}}
+{{< /clients-example >}}
+
+Add the three sets of user data to the database as
+[JSON]({{< relref "/develop/data-types/json" >}}) objects.
+If you use keys with the `user:` prefix then Redis will index the
+objects automatically as you add them:
+
+{{< clients-example java_home_json add_data >}}
+{{< /clients-example >}}
+
+You can now use the index to search the JSON objects. The
+[query]({{< relref "/develop/interact/search-and-query/query" >}})
+below searches for objects that have the text "Paul" in any field
+and have an `age` value in the range 30 to 40:
+
+{{< clients-example java_home_json query1 >}}
+{{< /clients-example >}}
+
+Specify query options to return only the `city` field:
+
+{{< clients-example java_home_json query2 >}}
+{{< /clients-example >}}
+
+Use an
+[aggregation query]({{< relref "/develop/interact/search-and-query/query/aggregation" >}})
+to count all users in each city.
+
+{{< clients-example java_home_json query3 >}}
+{{< /clients-example >}}
+
+See the [Redis query engine]({{< relref "/develop/interact/search-and-query" >}}) docs
+for a full description of all query features with examples.
