        This new query function improves performance significantly, but is still
        being tested for accuracy and edge cases.

        This only executes one query to PWS per population requested. The
        query includes wildcards for each token the user input.

        For example: "buffy anne summers" would become a query for
        display names matching:
            "*buffy* *summers*"

        In this example, PWS would return any of the following results:
            - buffy anne summers
            - buffy "the vampire slayer" summers
            - ubuffya alsummersia
            - buffy-anne summers
            - buffy anne summers-finn

        After the results have been filtered, they are sent to the
        NameSearchResultReducer, which is responsible for sorting
        these names into appropriate buckets by relevance.
