开发中，使用到LessThen-小于某个参数的逻辑查询，如下：

/// <summary>
/// 查询状态已发布（状态小于2）的政策要闻分页
/// </summary>
/// <param name="input"></param>
/// <returns></returns>    
public async Task<PagedDto<PageSearchOutput>> GetPageSearchResultAsync(PageSearchInput input)
    {
        var elasticSearchManager = LazyServiceProvider.LazyGetRequiredService<IElasticSearchManager>();
        var searchRequest = new SearchRequest<PageIndex>(Nest.Indices.Parse(PageExtensionConsts.IndexName));
        searchRequest.Sort = new List<ISort> { new FieldSort { Field = Infer.Field<PageIndex>(d => d.CreationTime), Order = SortOrder.Descending } };

        var filterList = new List<QueryContainer>{
            new NumericRangeQuery(){
                Field = Infer.Field<PageIndex>(d => d.Status),
                LessThan
