An encoded query string represents a complex filter on a list of records.

Use encoded query strings to include a filter as part of a URL parameter, such as the Navigate to a record or module using a URL, or as a reference qualifier to restrict the data that is selectable for a reference field.

To construct an encoded query string, generate a list query and then copy it from the list filter. This is the preferred method because the alternative is to create the string manually.

In order to create an encoded query string manually, you need to know the relevant table and field names and operators.
