我有一个以下模型类，该模型类用于在Elasticsearch中为文档建立索引。
public class SearchModel
{
public string Id { get; set; }
public string Category { get; set; }
public string CategoryId { get; set; }
public string SubCategory { get; set; }
public List<SearchItem> SearchItems = new List<SearchItem>();
}
public class SearchItem
{
public string ItemName { get; set; }
public string ItemValue { get; set; }
}
我想在Category，SubCategory和ItemValue中进行搜索，并返回所有SearchModel类。我当前的搜索方法是
var response = await _elasticClient.SearchAsync<SearchModel>(
s =>
//s.Query(q => q
// .Match(m => m
// .Field(f => f.Category)
// .Field(f => f.SubCategory)
// .Field(f => f.SearchItems)
// .Query(String.Format("*{0}*", query))
// )
//));
s.Query(q => q.QueryString(d => d.Query(String.Format("*{0}*", query))))
.From((page - 1) * pageSize)
.Size(pageSize));
示例搜索结果是

在c＃中，索引是通过以下代码完成的，还需要避免包含“ 5c65772d07894532bccfeba”之类的ID字段
var searchModel = new SearchModel();
var searchItems = new List<SearchItem>();
searchModel.Id = "5c65772d07894532bccfeba";
searchModel.Category = "Asset";
searchModel.CategoryId = "5c65772d07894532bccfeba";
searchModel.SubCategory = "test category";
var item1 = new SearchItem
{
ItemName = "SerialNumber",
ItemValue = "DP123"
};
searchItems.Add(item1);
var item2 = new SearchItem
{
ItemName = "SkuNumber",
ItemValue = "test"
};
searchItems.Add(item2);
var item3 = new SearchItem
{
ItemName = "WorkOrderNumber",
ItemValue = "TestOrder123"
};
searchItems.Add(item3);
var item4 = new SearchItem
{
ItemName = "ComponentId",
ItemValue = "5c65772d01577532bccfeba"
};
searchItems.Add(item4);
var item5 = new SearchItem
{
ItemName = "ComponentName",
ItemValue = "TestComponent"
};
searchItems.Add(item5);
searchModel.SearchItems = searchItems;
var response = await _elasticClient.IndexDocumentAsync(searchModel);
当我使用查询字符串作为SerialNumber中包含的'dp'时得到此结果。我想避免在id字段中搜索“ dp”。 我尝试了注释的代码，但未返回任何数据。如何解决此问题？
