[英]Elasticsearch.NET NEST Object Initializer syntax for a highlight request
I've got: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"
});
And I'm trying to add a highlighter filter but I'm not that familiar with the Object Initializer (OIS) C# syntax.我正在尝试添加一个荧光笔过滤器,但我对对象初始值设定项 (OIS) C# 语法不太熟悉。 I've checked NEST official pages and SO but can't seem to return any results for specifically the (OIS).
我已经检查了NEST 官方页面和 SO,但似乎无法针对(OIS)返回任何结果。
I can see the Highlight property in the Nest.SearchRequest class but I'm not experienced enough (I guess) to simply construct what I need from there - some examples and explanations as to how to employ a highlighter with OIS would be hot!我可以在 Nest.SearchRequest 类中看到 Highlight 属性,但我没有足够的经验(我猜)从那里简单地构建我需要的东西 - 关于如何使用带有 OIS的荧光笔的一些示例和解释会很热门!
This is the fluent syntax:这是流畅的语法:
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>"))));
and this is by object initialization: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);
UPDATE更新
NEST 7.x syntax: NEST 7.x 语法:
var searchQuery = new SearchRequest
{
Highlight = new Highlight
{
Fields = new FluentDictionary<Field, IHighlightField>()
.Add(Nest.Infer.Field<Document>(d => d.Name),
new HighlightField {PreTags = new[] {"<tag>"}, PostTags = new[] {"<tag>"}})
}
};
My document class:我的文档类:
public class Document
{
public int Id { get; set; }
public string Name { get; set; }
}
