c# - C#Nest-ElasticSearch

Question

我是ElasticSearch的新手，并且正在使用NEST运行查询。我需要能够向查询中添加X个过滤条件。

现在，我的查询看起来像这样:

var page = new Page
{
    Id = 1,
    Name = "JR-11 Hyper black"
};

var tags = new Dictionary<string, string[]>
{
    { "Size", new[] { "16", "17", "18" }},
    { "Color", new[] { "Bronze", "Hyper Black", "Flat Black" }}
};

page.Tags = tags;

ElasticClient.Index(page, idx => idx.Index("pages"));

var result = ElasticClient.Search<Page>(
    body => body.Query(query => query.ConstantScore(
        csq => csq.Filter(filter => filter.Term("tags.Size", "17" ))))
    .Take(1000));

var pages = result.Documents.ToList();

我遇到的问题是 csq.Filter(filer => filter.Term("tags.Storlek")
我需要能够添加动态数量的此类过滤器。我正在使用的2.3版本的文档中找不到任何内容。

Answer 1

Fluent API应该允许这样的事情:

string[] filterTerms = { ... };

var result = ElasticClient.Search<Page>(
    body => body.Query(query => query.ConstantScore(
    csq =>
    {
        var combinedFilters = csq.Filter(filter => filter.Term("tags.Size", "17" ));

        // add an additional, dynamic amount of filters
        foreach (string filterTerm in filterTerms)
            combinedFilters = combinedFilters.Filter(filter => filter.Term(filterTerm, ...));

        return combinedFilters;
    }))
    .Take(1000));
