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