Way to set lucene filters on queries

[Lassi Immonen]

Lucene has DuplicateFilter which could be used to filter distinct fields on documents. It would be nice to be able to utilize this filter in queries. For example query.where(name.distinct(LAST_OCCURRENCE).eq("Timo")) or some other neat way.

Added support for distinct(path) and general filtering :

    /**
     * Add a DuplicateFilter for the field of the given property path
     *
     * @param property
     * @return
     */
    public Q distinct(Path<?> property){
        return filter(new DuplicateFilter(serializer.toField(property)));
    }

    /**
     * Apply the given Lucene filter to the search results
     *
     * @param filter
     * @return
     */
    @SuppressWarnings("unchecked")
    public Q filter(Filter filter){
        this.filter = filter;
        return (Q)this;
    }
