開發中，使用到LessThen-小于某個參數的邏輯查詢，如下：

/// <summary>
/// 查詢狀態已發布（狀態小于2）的政策要聞分頁
/// </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 = (byte)PageStatus.Revoked //小于2的查詢出來}};if (input.IsEmpty())searchRequest.Query = new BoolQuery{Filter = filterList};else{var shouldList = new List<QueryContainer>();if (!input.QueryText.IsNullOrWhiteSpace()){var titleMatchQuery = new MatchQuery{Field = Infer.Field<PageIndex>(d => d.Title),Query = input.QueryText};var contentMatchQuery = new MatchQuery{Field = Infer.Field<PageIndex>(d => d.Content),Query = input.QueryText};shouldList.Add(titleMatchQuery);shouldList.Add(contentMatchQuery);searchRequest.Sort = new List<ISort> { new FieldSort { Field = "_score", Order = SortOrder.Descending } };}if (!input.Category.IsNullOrWhiteSpace()){filterList.Add(new TermQuery { Field = Infer.Field<PageIndex>(d => d.Category), Value = input.Category });}if (input.Province.HasValue){filterList.Add(new TermQuery { Field = Infer.Field<PageIndex>(d => d.Province), Value = input.Province });}if (input.City.HasValue){filterList.Add(new TermQuery { Field = Infer.Field<PageIndex>(d => d.City), Value = input.City });}var query = new BoolQuery{Should = shouldList,Filter = filterList};if (shouldList.Any()){query.MinimumShouldMatch = 1;}searchRequest.Query = query;}var queryDslJson = elasticSearchManager.GetQueryDslJson(searchRequest);var esResponse = await elasticSearchManager.SearchAsync<PageIndex>(searchRequest,(input.PageIndex - 1) * input.PageSize,input.PageSize);var pageIndices = esResponse.Documents;var ids = pageIndices.Select(i => i.Id).ToList();var qtos = await _queryRepository.GetPagesHitsAsync(ids);var outputs = pageIndices.Select(i =>{var areaIds = new List<int>();var area = string.Empty;areaIds.Add(i.Province);if (i.City.HasValue)areaIds.Add(i.City.Value);if (areaIds.Any())area = _queryRepository.GetAreaAsync(areaIds).Result;return new PageSearchOutput{Id = i.Id,Title = i.Title,Content = i.Content,CategoryName = PageCategory.FromValue(i.Category).DisplayName,TitlePicture = i.TitlePicture,CreationTime = i.CreationTime.ToDateTimeStr(),Status = ((PageStatus)i.Status).GetDescription(),Area = area,Hits = qtos.FirstOrDefault(qto => qto.Id == i.Id)?.Hits};});return new PagedDto<PageSearchOutput>(esResponse.Total, outputs.ToList());}

但是通過

var queryDslJson = elasticSearchManager.GetQueryDslJson(searchRequest);

轉json得到的內容如下：LessThen后參數內容轉義成2.0了，

這是因為LessThen是double?類型的，但是es中保存的2，所以導致查詢出來的結果不是預期的，把狀態=2的數據也查詢出來了

{"query": {"bool": {"filter": [{"range": {"status": {"lt": 2.0}}}]}},"sort": [{"creationTime": {"order": "desc"}}]
}

所以但是修改成

/// <summary>
/// 查詢狀態已發布（狀態小于2）的政策要聞分頁
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
