Configuring Data Sources

About data sources
Every instance of a component that needs to query the MDEX Engine is backed by a particular data source. That data source, which represents a pointer to a specific MDEX Engine, is used to maintain application state for each user's session.

Configuring data sources
Data sources and query states are how the Discovery Framework represents connections to MDEX Engines and queries to those MDEX Engines. This section discusses how to create and configure data sources, and outlines the default interaction model between related data sources.

Data source role-based security
The default MDEXSecurityManager implementation supports the configuration of filters associated with Liferay roles that have been assigned to a user's login.

Data source relationships
This topic describes the relationship between parent and child data sources.

Provided QueryFunction classes
This topic defines the QueryFunction classes included in the Discovery Framework.

Obtaining data source results
The ENEQueryResults class from the Presentation API is used to represent results of queries.
