# Automatic Query Guidance

Automatic Query Guidance (AQG) is a broad technique of analysis of a document set to determine important topics and phrases (called elements) in the set. More importantly, the elements are returned with a variety of information to allow you to determine more complex relationships and use the information for a number of different use cases. These include:

- automatic thesaurus generation

- rapid clustering of query result sets

- word-sense disambiguation

- query refinement

- noun phrase identification

You can apply AQG to any situation in which analysis of co-occurring elements can be used to drive functionality. You can also create custom functionality by using the information in an appropriate way.

AQG is driven using the Query action with the query parameter `QuerySummary`, which returns a list of elements and information on each.

The following sections describe a little more about `QuerySummary`, and how you can use it:
