與小面的陣列

我將一些公司的指數，其中國家屬性Elasticsearch數據聚合是國家代碼的數組：與小面的陣列

curl -XPUT 'http://localhost:9200/test/company/10' -d '{"countries" : ["CH", "CN"], "name" : "company10"}' 
curl -XPUT 'http://localhost:9200/test/company/11' -d '{"countries" : ["AT", "CH", "CN", "DE", "EN", "FR"], "name" : "company11"}' 
curl -XPUT 'http://localhost:9200/test/company/12' -d '{"countries" : ["AT", "CN", "EN", "FR"], "name" : "company12"}' 
curl -XPUT 'http://localhost:9200/test/company/13' -d '{"countries" : ["CH", "CN", "HU"], "name" : "company13"}' 
curl -XPUT 'http://localhost:9200/test/company/14' -d '{"countries" : ["CH", "CN", "EN", "FR"], "name" : "company14"}' 
curl -XPUT 'http://localhost:9200/test/company/15' -d '{"countries" : ["AT", "CN", "DE", "EN", "FR", "HU"], "name" : "company15"}' 
curl -XPUT 'http://localhost:9200/test/company/16' -d '{"countries" : ["AT", "BE", "CH", "DE", "EN", "FR", "HU"], "name" : "company16"}' 
curl -XPUT 'http://localhost:9200/test/company/17' -d '{"countries" : ["BE", "CN", "EN"], "name" : "company17"}' 
curl -XPUT 'http://localhost:9200/test/company/18' -d '{"countries" : ["AT", "CH", "CN", "DE"], "name" : "company18"}' 
curl -XPUT 'http://localhost:9200/test/company/19' -d '{"countries" : ["AT", "CH", "CN", "DE", "EN", "FR", "HU"], "name" : "company19"}' 
curl -XPUT 'http://localhost:9200/test/company/20' -d '{"countries" : ["EN", "FR"], "name" : "company20"}' 
curl -XPUT 'http://localhost:9200/test/company/21' -d '{"countries" : ["AT", "BE", "DE", "FR", "HU"], "name" : "company21"}' 
curl -XPUT 'http://localhost:9200/test/company/22' -d '{"countries" : ["AT", "BE", "CH", "DE", "EN", "FR", "HU"], "name" : "company22"}' 
curl -XPUT 'http://localhost:9200/test/company/23' -d '{"countries" : ["AT", "BE", "CH", "CN", "DE", "EN", "HU"], "name" : "company23"}' 
curl -XPUT 'http://localhost:9200/test/company/24' -d '{"countries" : ["AT", "BE", "CH", "CN", "DE", "EN", "FR"], "name" : "company24"}' 
curl -XPUT 'http://localhost:9200/test/company/25' -d '{"countries" : ["AT", "BE", "CH", "DE", "EN", "FR"], "name" : "company25"}' 
curl -XPUT 'http://localhost:9200/test/company/26' -d '{"countries" : ["AT", "BE", "CH", "CN", "DE", "EN", "FR", "HU"], "name" : "company26"}' 
curl -XPUT 'http://localhost:9200/test/company/27' -d '{"countries" : ["AT", "EN", "FR"], "name" : "company27"}' 
curl -XPUT 'http://localhost:9200/test/company/28' -d '{"countries" : ["CN"], "name" : "company28"}' 
curl -XPUT 'http://localhost:9200/test/company/29' -d '{"countries" : ["BE", "CH", "CN", "EN", "FR"], "name" : "company29"}' 
curl -XPUT 'http://localhost:9200/test/company/30' -d '{"countries" : ["CN"], "name" : "company30"}'

我想COUNTRY_CODE到公司彙總（國家屬性），請統計每個國家有多少家公司。

可悲的是，即使是這樣（爲AT代碼計數）不工作：

curl -XGET 'http://localhost:9200/test/company/_search?pretty=true' -d ' 
{"query" : { "match_all" : {} }, 
"facets" : { 
    "foo" : { 
     "filter" : { 
     "term" : { "countries" : "AT" } 
     } 
    } 
    } 
} 
'

我越來越：

...

"facets" : { 
    "foo" : { 
    "_type" : "filter", 
    "count" : 0 
    } 
}

我是什麼做錯了？

只是'AT'不工作？你嘗試過'CN'嗎？ –

現在，我也嘗試過CN，與AT在facet部分的相同響應 – astropanic

hmm ok，我想這可能是由於ES沒有索引停用詞（http://stackoverflow.com/questions/17883936/is-there -a路至轉義elasticsearch一站式的話）。但是如果CN也行不通，那就不可能是這樣。 –

我認爲這是因爲沒有分析過濾器。 AT是停用詞，因此它沒有編入索引。您可以使用_analyze API：http://localhost:9200/test/_analyze?text=AT&field=countries進行檢查。

您可以檢查非停用詞，例如CN，但這是小寫的http://localhost:9200/test/_analyze?text=CN&field=countries。因此cn（實際上存儲在索引中）與您facet過濾器中的CN不匹配。

您可以嘗試修改您的搜索，以小寫的國家縮寫：

curl -XGET 'http://localhost:9200/test/company/_search?pretty=true' -d ' 
{"query" : { "match_all" : {} }, 
"facets" : { 
    "foo" : { 
     "filter" : { 
     "term" : { "countries" : "cn" } 
     } 
    } 
    } 
}'

得到

"facets" : { 
    "foo" : { 
     "_type" : "filter", 
     "count" : 15 
    } 
    }

但我認爲你應該對國家的定義映射到"index":"not_analyzed"避免這種情況（包括禁用詞和降價）

# Delete index 
# 
curl -XDELETE 'http://localhost:9200/test' 

# Create with mapping 
# 
curl -XPUT 'http://localhost:9200/test/' -d '{ 
    "mappings": { 
    "company": { 
     "properties": { 
     "countries": { "type": "string", "index" : "not_analyzed" } 
     } 
    } 
    } 
}'

問題的真棒解釋，非常感謝。它的作用就像一個魅力;） – astropanic

我有同樣的問題，我已經添加索引：not_analyzed字段'country_code'，認爲有些國家'，'是'等等被排除在方面。我繼續檢查。現在我剛剛在國家代碼前加了'_'，所以它存儲了_at，_be等。 – Alex

或者@vhyza是對的，我只有2種類型 - 一種是提供的映射，另一種是沒有自動處理的：not_indexed，我的fauld ，所以是 - index：not_analyzed解決了這個問題。 – Alex
