回到长期计数使用术语在一个文档中搜索弹性突间 [英] Returning term count for a single document using the terms facet in elastic search

问题描述

说我有以下的搜索查询...

Say I have the following search query...

POST /topics/_search
{
    "fields": [
       "topic_attachment",
       "topic_replies",
       "topic_status"
    ],
    "query" : {
        "filtered" : {
            "query" : {
                "term" : { 
                    "_id" : "5478"
                }
            }
        }           
    },
    "facets": {
       "text": {
          "terms": {
             "field": "text",
             "size": 10,
             "order": "count"
            }
       }
    }
}

此搜索的结果是以下

{
   "took": 93,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 1,
      "max_score": 1,
      "hits": [
         {
            "_index": "topics",
            "_type": "full-topic",
            "_id": "5478",
            "_score": 1,
            "fields": {
               "topic_replies": 1141,
               "topic_status": 0,
               "topic_attachment": false
            }
         }
      ]
   },
   "facets": {
      "text": {
         "_type": "terms",
         "missing": 0,
         "total": 8058,
         "other": 8048,
         "terms": [
            {
               "term": "ω",
               "count": 1
            },
            {
               "term": "œyouâ",
               "count": 1
            },
            {
               "term": "œyou",
               "count": 1
            },
            {
               "term": "œwhisperedâ",
               "count": 1
            },
            {
               "term": "œwalt",
               "count": 1
            },
            {
               "term": "œunderstandingâ",
               "count": 1
            },
            {
               "term": "œtieâ",
               "count": 1
            },
            {
               "term": "œthe",
               "count": 1
            },
            {
               "term": "œpersonally",
               "count": 1
            },
            {
               "term": "œnappiesâ",
               "count": 1
            }
         ]
      }
   }
}

每个学期都有正好1.计数这是为什么？我知道本文档中的文本在普通不止一个学期。这是因为这个词只计数每增加一次文件？如果让我怎么算一个术语不止一次从一个单一的文件？

Each term has a count of exactly 1. Why is this? I know the text from this document has more than one term in common. Is this because the term count only increments once per document? If so how do I count a term more than once from a single document?

推荐答案

这是该文件的计数，而不是长期的频率。幸运的是新的聚合模块（用于更换在1.0.Beta2引进方面）计数已更名为 doc_count 澄清的是什么。

That's the document count, not the term frequency. Luckily with the new aggregations module (replacement for facets introduced in 1.0.Beta2) count has been renamed to doc_count to clarify what it is.
