python - 在 Elasticsearch 中过滤特定字段上的查询

Question

我有这样的文件

  {
    _index: "logstash-2015.11.30",
    _type: "hadoopgeneric",
    _id: "AVFVsF6ypMu_z_qvIUgL",
    _score: null,
    _source: {
             @timestamp: "2015-11-30T00:00:00.017Z",
             message: "selector : 48 - Element found for using multiple selectors using query .js-product-brand.product-brand",
             @version: "1",
             host: "ip-x-x-x-x",
             path: "/logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr",
             type: "hadoopgeneric",
             thread_id: "15119",
             thread_name: "MainThread",
             component_name: "Page",
             severity: "DEBUG",
             env: "STG",
             role: "spider",
             ip: "x.x.x.x",
             tags: [
                 "processed"
             ]
            },
   }

我必须过滤其中包含路径 /logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr的那些文档(特别是在 path字段中)

我尝试了此一般搜索查询 http://localhost:9200/logstash-*/_search?pretty=true&q="/logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr"&sort=@timestamp&size=100000
它给了我结果，但现在我正在考虑尝试通过像这样触发此查询来仅在 path字段中进行搜索(此查询中没有任何结果)- http://localhost:9200/logstash-*/_search?pretty=true&q="path: /logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr"&sort=@timestamp&size=100000
我正在 flex 搜索中浏览这份文档 Term Query。但是我不确定如何在 flex 搜索中传递诸如post参数之类的查询。我正在使用python库发出发布请求以进行 flex 搜索

以下是我到目前为止尝试过的

esurl = http://localhost:9200/logstash-*/_search
r = requests.post(esurl,data={"term":{'path':'/logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr'}})
r.text

{"error":"SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[5D_RNDQPRf6xyLO1suIoCA][logstash-2015.11.30][0]: RemoteTransportException[[ip-x-x-x-x-elkstorage][inet[/x.x.x.x:9300]][indices:data/read/search[phase/query]]]; nested: SearchParseException[[logstash-2015.11.30][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [_na_]]]; nested: ElasticsearchParseException[Failed to derive xcontent]; }{[o8jLb8P5SWOfsCo78eUlHg][logstash-2015.12.01][0]: RemoteTransportException[[ip-x-x-x-x-elkstorage][inet[/x.x.x.x:9300]][indices:data/read/search[phase/query]]]; nested: SearchParseException[[logstash-2015.12.01][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [_na_]]]; nested: ElasticsearchParseException[Failed to derive xcontent];}

Answer 1

q参数似乎错误("字符位置错误)，请尝试以下操作:

http://localhost:9200/logstash-*/_search?pretty=true&q=path:"/logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr"&sort=@timestamp&size=100000

另一方面，查询一词有效，但必须在 query键之内，例如:

import requests
import json

esurl = "http://localhost:9200/logstash-*/_search"
r = requests.post(esurl,data=json.dumps({"query": {"term":{'path':'/logs/stats/container/application_1448508514184_0178/container_e06_1448508514184_0178_01_003568/stderr'}}}))
