17、学习Lucene3.5索引之使用Filter(过滤器)搜索

/**
     * 在搜索到的结果中再用过滤器过滤：
     * TermRangeFilter()：范围过滤器
     * NumericRangeFilter.newIntRange()：整型范围过滤器
     * QueryWrapperFilter():Query封装过滤器（可以封装一个Query来限制搜索范围）
     */
    @Test
    public void testFilter(){
        //TermRangeFilter(String fieldName, String lowerTerm, String upperTerm,boolean includeLower, boolean includeUpper)
        Filter filter1 = new TermRangeFilter("filename","打火", "打火", true, true);
        Filter filter2 = NumericRangeFilter.newIntRange("size", 400, 450, true, true);
        Filter filter3 = new QueryWrapperFilter(new WildcardQuery(new Term("filename","?草")));

//        SortUtil.searchByFilter("公主", filter1);
//        SortUtil.searchByFilter("公主", filter2);
        SortUtil.searchByFilter("公主", filter3);

    }
