With the user defined queries, you can define any query condition - this is the default query mode.
Depending on the active edit mode you get one of three different query option panels as shown in the pictures below.
In the lower part you may adjust the Query conditions to restrict the Query results shown in the upper part of the panel. In search texts you may enter SQL wildcards to specify ambigious conditions to match the data. By default only the most importand query conditions are displayed.

in a list. The regular description query is not capable to select descriptions with

is accessible from the menu Query ->
