The filter's declared fields for one layer: field — and subField for a taxonomy
descriptor — of every descriptor that lists the layer, text and proximity excepted.
The fields the listed descriptors test on that layer; none when the filter is disabled
or no descriptor lists the layer.
Example
filterDeclaredFields({ enabled:true, fields: [{ id:"c", kind:"taxonomy", field:"categoryId", subField:"subCategoryId", layers: ["candelabres"] }] }, "candelabres"); // → the category field and the sub-category field
