Question

在一个ES请求中发送3个单独的查询

我正在使用NEST客户端使用下面的函数将查询发送到弹性搜索

IElasticClient _elasticClient.LowLevel.Msearch<string>(query).Body;

使用curl命令作为原始查询传递绝对正常，但NEST MSearch只返回“event_results”和“venue_results”而不是“location_results”

curl -XPOST localhost:9200/_msearch -d '
{"index" : "search_results"}
{ "size": 0, "query": { "bool": { "must": [ { "term": { "partnersites": "16" } }, { "match_phrase_prefix": { "name": "manchester" } } ] } }, "aggs": { "event_results": { "terms": { "field": "name.keyword", "size": 1 }, "aggs": { "top_tag_hits": { "top_hits": { "size": 1, "_source": [ "name", "groupedName", "groupedDisplayName", "groupedUrl", "eventCode", "venueName", "venueTown", "venueId", "venueUrl", "media", "categories.name" ] } } } } } }
{"index" : "search_results2"}
{ "size": 0, "query": { "bool": { "must": [ { "term": { "partnersites": "16" } }, { "match_phrase_prefix": { "venueName": "Manchester" } } ] } }, "aggs": { "venue_results": { "terms": { "field": "name.keyword", "size": 1 }, "aggs": { "top_tag_hits": { "top_hits": { "size": 1, "_source": [ "name", "groupedName", "groupedDisplayName", "groupedUrl", "eventCode", "venueName", "venueTown", "venueId", "venueUrl", "media", "categories.name" ] } } } } } }
{"index" : "search_results3"}
{ "size": 0, "query": { "bool": { "must": [ { "term": { "partnersites": "16" } }, { "match_phrase_prefix": { "venueTown": "manchester" } } ] } }, "aggs": { "location_results": { "terms": { "field": "name.keyword", "size": 1 }, "aggs": { "top_tag_hits": { "top_hits": { "size": 1, "_source": [ "name", "groupedName", "groupedDisplayName", "groupedUrl", "eventCode", "venueName", "venueTown", "venueId", "venueUrl", "media", "categories.name" ] } } } } } }
'

你们中有谁知道问题出在哪里？

Answer 1

只要有可能，您不想使用“LowLevel”内容。相反，请使用IElasticClient上可用的内容。以下是如何使用IElasticClient.MultiSearch使用流利语法（这是执行此操作的首选方法）运行3次搜索的示例。

var mSearchResponse = ElasticClient.MultiSearch(msearch => msearch
    .Search<RedemptionES>(
        s1 => s1.Query(
            q=>q.Term(
                t=> t.OnField(f=> f.Id).Value("123")
            )
        )
    )
    .Search<RedemptionES>(
        s2 => s2.Query(
            q => q.Term(
                t => t.OnField(f => f.Id).Value("456")
            )
        )
    )
    .Search<RedemptionES>(
        s3 => s3.Query(
            q => q.Term(
                t => t.OnField(f => f.Id).Value("789")
            )
        )
    )
);

问题在于缩进。试试这个：

    public static string qu = @"{""index"" : ""search_results""}
{ ""size"": 0, ""query"": { ""bool"": { ""must"": [ { ""term"": { ""partnersites"": ""16"" } }, { ""match_phrase_prefix"": { ""name"": ""manchester"" } } ] } }, ""aggs"": { ""event_results"": { ""terms"": { ""field"": ""name.keyword"", ""size"": 1 }, ""aggs"": { ""top_tag_hits"": { ""top_hits"": { ""size"": 1, ""_source"": [ ""name"", ""groupedName"", ""groupedDisplayName"", ""groupedUrl"", ""eventCode"", ""venueName"", ""venueTown"", ""venueId"", ""venueUrl"", ""media"", ""categories.name"" ] } } } } } }
{""index"" : ""search_results2""}
{ ""size"": 0, ""query"": { ""bool"": { ""must"": [ { ""term"": { ""partnersites"": ""16"" } }, { ""match_phrase_prefix"": { ""venueName"": ""Manchester"" } } ] } }, ""aggs"": { ""venue_results"": { ""terms"": { ""field"": ""name.keyword"", ""size"": 1 }, ""aggs"": { ""top_tag_hits"": { ""top_hits"": { ""size"": 1, ""_source"": [ ""name"", ""groupedName"", ""groupedDisplayName"", ""groupedUrl"", ""eventCode"", ""venueName"", ""venueTown"", ""venueId"", ""venueUrl"", ""media"", ""categories.name"" ] } } } } } }
{""index"" : ""search_results3""}
{ ""size"": 0, ""query"": { ""bool"": { ""must"": [ { ""term"": { ""partnersites"": ""16"" } }, { ""match_phrase_prefix"": { ""venueTown"": ""manchester"" } } ] } }, ""aggs"": { ""location_results"": { ""terms"": { ""field"": ""name.keyword"", ""size"": 1 }, ""aggs"": { ""top_tag_hits"": { ""top_hits"": { ""size"": 1, ""_source"": [ ""name"", ""groupedName"", ""groupedDisplayName"", ""groupedUrl"", ""eventCode"", ""venueName"", ""venueTown"", ""venueId"", ""venueUrl"", ""media"", ""categories.name"" ] } } } } } }
";

var result = _elasticClient.LowLevel.Msearch<string>(qu).Body; // Query ES for results.

ElasticSearch Nest Msearch fn并未带来所有结果
