Do you have any example queries you are wanting? Are the categories
hierarchical?

A map function of:
function (doc) {
    if (doc.type !=3D=3D "product") return;

    //pretty sure forEach() is supported
    doc.categories.forEach(function (cat) {
         emit(cat, null);
    });
}

would let to retrieve things like "all products with a category of '1'"
something like a query parameter of: ?key=3D1
