contains("item")
Returns true if the note evaluated from item is a direct child of the current note or, put conversely, if the note is the parent of item. Thus it can be thought of as an "is parent of" operator - and as such a counterpart to the "is a child of" operator inside().
The item parameter must be quoted unless an attribute reference. Ways to define item.
in the query creation pop-ups of agent and Find dialogs this function is listed as "is container of".
This replaces the legacy #contains query operator.
Checking attribute values, as opposed to object containment. There are a range of other tools to check if a String-, List- or Set-type attribute's value contains a desired search pattern. For String attributes there are String.contains() and String.icontains(). List and Set date type attrinbutes also support .contains() and .icontains() though in this context the scope of pattern matches is slightly different from that with a String-type attribute. Single words alone can be checked using word(), which works across $Name, $Text and all String-type attributes.
