                             Map<String,​Float> fieldBoosts)
        Add an alias to this query parser.
        field - the field name that should trigger alias mapping
        fieldBoosts - the mapping from fieldname to boost value that should be used to build up the clauses of the DisjunctionMaxQuery.
        tiebreaker - to the tiebreaker to be used in the DisjunctionMaxQuery

        Delegates to the super class unless the field has been specified as an alias -- in which case we recurse on each of the aliased fields, and the results are composed into a DisjunctionMaxQuery. (so yes: aliases which point at other aliases should work)
