Using the Query Edit Assistant
The Assistant tab enables creation of multi-parameter queries without needing to know ERQL language.
A query bar similar to that presented in section
"Using the Query Toolbar" enables selection of the query target object type.

The assistant query bar does not enable query from a selection of object types as is the case for the workspace query bar.
You can execute a simple query using this bar, or execute a query using the parameters that appear in the tree.
