ElasticSearch 的 NEST TermQuery 不起作用

Question

给定

string author = "John Smith";

以下使用 NEST 的 lambda 查询有效：

string firstname = author.Split().First().ToLower();
var searchResults = client.Search<Magazine>(s => s.From(0).Size(5000).Query(q => q.Term(p => p.Author, author)));

但是，使用 OIS（对象初始化语法）的相同查询不起作用：

author = author.Split().First().ToLower();

QueryContainer query = new TermQuery
{
   Field = "Author",
   Value = author
};

var searchRequest = new SearchRequest
{
   From = 0,
   Size = 10,
   Query = query
};

var searchResults = client.Search<Magazine>(searchRequest);

怎么了？

Answer 1

尝试使用驼峰形式的字段名称：- 我认为在使用 OIS 语法或原始查询时需要这样做。

author = author.Split().First().ToLower();

QueryContainer query = new TermQuery
{
   Field = "author",
   Value = author
};

var searchRequest = new SearchRequest
{
   From = 0,
   Size = 10,
   Query = query
};

var searchResults = client.Search<Magazine>(searchRequest); 

Answer 2

为QueryContainer添加“关键字”后缀：

QueryContainer query = new TermQuery
{
   Field = "Author",
   Value = author
};
query.Suffix("keyword");
var searchRequest = new SearchRequest
{
   From = 0,
   Size = 10,
   Query = query
};

var searchResults = client.Search<Magazine>(searchRequest); 

试一试就可以了
