我有:
var result = _client.Search<ElasticFilm>(new SearchRequest("blaindex", "blatype")
{
From = 0,
Size = 100,
Query = titleQuery || pdfQuery,
Source = new SourceFilter
{
Include = new []
{
Property.Path<ElasticFilm>(p => p.Url),
Property.Path<ElasticFilm>(p => p.Title),
Property.Path<ElasticFilm>(p => p.Language),
Property.Path<ElasticFilm>(p => p.Details),
Property.Path<ElasticFilm>(p => p.Id)
}
},
Timeout = "20000"
});
我正在尝试添加一个荧光笔过滤器,但我并不熟悉Object Initializer(OIS)C#语法。我已经检查了NEST official pages和SO,但似乎无法返回任何具体的(OIS)结果。
我可以在Nest.SearchRequest类中看到Highlight属性,但我没有足够的经验(我猜)只是简单地构建我需要的东西 - 关于如何使用荧光笔的一些示例和解释OIS 会很热!

这是流利的语法:
var response= client.Search<Document>(s => s
.Query(q => q.Match(m => m.OnField(f => f.Name).Query("test")))
.Highlight(h => h.OnFields(fields => fields.OnField(f => f.Name).PreTags("<tag>").PostTags("</tag>"))));
这是通过对象初始化:
var searchRequest = new SearchRequest
{
Query = new QueryContainer(new MatchQuery{Field = Property.Path<Document>(p => p.Name), Query = "test"}),
Highlight = new HighlightRequest
{
Fields = new FluentDictionary<PropertyPathMarker, IHighlightField>
{
{
Property.Path<Document>(p => p.Name),
new HighlightField {PreTags = new List<string> {"<tag>"}, PostTags = new List<string> {"</tag>"}}
}
}
}
};
var searchResponse = client.Search<Document>(searchRequest);
我的文档类:
public class Document
{
public int Id { get; set; }
public string Name { get; set; }
}
