Bug Description

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;
    }
