# Verity Query Language (VQL) Search

If you have upgraded to HPE IDOL Server from a legacy Verity installation, you can carry on using Verity Query Language (VQL) by typing it as the query text and adding the VQL parameter to the query string.

For example:

    http://localhost:9000/action=Query&Text=cat <AND> dog&VQL=True

This query returns only documents that contain both `cat` and `dog`.

    http://localhost:9000/action=Query&Text=red <NEAR/1> green&VQL=True

This query returns only documents in which the term `red` is adjacent to the term `green`. This query returns documents that contain the phrases `red green`, `green red` or `green and red` (`and` is a stop word and is therefore ignored). Documents that contain `red orange green` do not return (because the terms are not close enough to each other).

Note: You cannot include the FieldText parameter in a VQL query.
