[英]How to search a elasticsearch index by partial text of a field in the indexed document?
[英]Unable to search attachment type field in an ElasticSearch indexed document
搜索沒有返回任何結果,盡管我有一個應與查詢匹配的文檔。
我確實每個https://github.com/elasticsearch/elasticsearch-mapper-attachments安裝了ElasticSearch映射器附件插件。 我也用谷歌搜索了該主題,並在堆棧溢出中瀏覽了類似的問題,但沒有找到答案。
這是我在Windows 7命令提示符下鍵入的內容:
c:\Java\elasticsearch-1.3.4>curl -XDELETE localhost:9200/tce
{"acknowledged":true}
c:\Java\elasticsearch-1.3.4>curl -XPUT localhost:9200/tce
{"acknowledged":true}
c:\Java\elasticsearch-1.3.4>curl -XPUT localhost:9200/tce/contact/_mapping -d{\"
contact\":{\"properties\":{\"my_attachment\":{\"type\":\"attachment\"}}}}
{"acknowledged":true}
c:\Java\elasticsearch-1.3.4>curl -XPUT localhost:9200/tce/contact/1 -d{\"my_atta
chment\":\"SGVsbG8=\"}
{"_index":"tce","_type":"contact","_id":"1","_version":1,"created":true}
c:\Java\elasticsearch-1.3.4>curl localhost:9200/tce/contact/_search?pretty
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
"_index" : "tce",
"_type" : "contact",
"_id" : "1",
"_score" : 1.0,
"_source":{"my_attachment":"SGVsbG8="}
} ]
}
}
c:\Java\elasticsearch-1.3.4>curl localhost:9200/tce/contact/_search?pretty -d{\"
query\":{\"term\":{\"my_attachment\":\"Hello\"}}}
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
請注意,“ Hello”的base64編碼值是“ SGVsbG8 =“,這是我已插入文檔的“ my_attachment”字段中的值。
我假設已正確部署了mapper-attachments插件,因為在執行上述映射命令時沒有出現錯誤。
任何幫助將不勝感激。
哪個分析器針對my_attachment
字段運行?
如果它是標准分析器(看不到任何列出的內容),則文本中的Hello
將在索引中變為小寫。
例如,當進行術語搜索時(沒有分析器)-嘗試搜索“ hello
curl localhost:9200/tce/contact/_search?pretty -d'
{"query":
{"term":
{"my_attachment":"hello"
}}}'
您還可以查看哪些術語已添加到索引中:
curl 'http://localhost:9200/tce/contact/_search?pretty=true' -d '{
"query" : {
"match_all" : { }
},
"script_fields": {
"terms" : {
"script": "doc[field].values",
"params": {
"field": "my_attachment"
}
}
}
}'
