The FILTER_CHILD_VALUES field is a special field that controls the ability to return, or not return, all matching repeating rows from a query. When this field is placed on a search query layout, a checkbox will appear to the end user when they are using the Standard Query screen. When this is not checked, a query that generates repeating row records will return all the repeating rows within an issue. When it is checked, the query will only return repeating row records that match the remaining filters in the query.
If the user has selected Advanced Query mode, then the option appears a a checkbox at the top of the filter selection list.
Before this field can be placed on a search layout, the behavior setting named FILTER_CHILD_VALUES must be set to have a value of USER.
