AttributeFilter

Filters the search results based on document attributes or fields.

You can filter results using attributes for your particular documents. The attributes must exist in your index. For example, if your documents include the custom attribute "Department", you can filter documents that belong to the "HR" department. You would use the EqualsTo operation to filter results or documents with "Department" equals to "HR".

You can use AndAllFilters and OrAllFilters in combination with each other or with other operations such as EqualsTo. For example:

AndAllFilters

• EqualsTo: "Department", "HR"

• OrAllFilters

• ContainsAny: "Project Name", ["new hires", "new hiring"]

This example filters results or documents that belong to the HR department AND belong to projects that contain "new hires" OR "new hiring" in the project name (must use ContainAny with StringListValue). This example is filtering with a depth of 2.

You cannot filter more than a depth of 2, otherwise you receive a ValidationException exception with the message "AttributeFilter cannot have a depth of more than 2." Also, if you use more than 10 attribute filters in a given list for AndAllFilters or OrAllFilters, you receive a ValidationException with the message "AttributeFilter cannot have a length of more than 10".
