Run a query to test or debug

The Query page of the LQE administration console can be used to test queries or debug unusual query results in a product consuming the LQE index. The Query page is used to write one-off SPARQL queries to access the LQE data directly. Queries cannot be stored in LQE. It can be found at this URL: https://[server]:[port]/lqe/web/query
You must reauthorize LQE to query on your behalf for all the applications being queried by LQE. You must reauthorize for each web browser session. Depending on which applications you have already authorized for your browser session, you may be prompted to reauthorize.
Note: Since each data source registers your user ID as being logged into the tool, this uses a license for each tool for the duration of the authorization.

For each data source you want to query click Authorize and enter your user ID and password if prompted. If you do not want your query to run against a data source you must explicitly Ignore it (rather than leaving it as Authorization Required). You can use this to filter the results returned in the query page, or you can authorize against all data sources to see the complete data set returned by the LQE query.
Note: If you have chosen to Ignore a data source this selection is cached for a short period allowing you to run several queries. You can return to the User Authorization page and click Stop Ignoring if you want to include this data source in additional queries.
There are two ways to execute a query against the LQE index:
SPARQL

Your query returns results in a table sorted by a relevancy ranking score.
