在elasticSearch中查询时定义分析器 [英] Defining analyzer while querying in elasticSearch

问题描述

我非常喜欢弹性搜索，只需要一些澄清：
我们可以在查询搜索服务器时定义分析器。我尝试使用文本和字段查询，它工作正常：

查询：

  curl -XPOST http：// localhost：9200 / test / user / _search？ -d'{query：{
text：{_all：{query：Vaibhav，analyzer：
lowercase_keyword}}}}'
  

结果：

  { 花：144， TIMED_OUT：假， _碎片：{ 总：5， 成功：5， 失败：0}， 命中：{ 总：1， max_score：0.10848885，hits：{_ index：test，_ type：user，_ id：1，_ score：0.10848885，
_source 
first_name：Vaibhav，
last_name：saini，
password：pwd
  

但是当我尝试用term / prefix / wildcard查询做同样的事情时，我得到例外：

查询：

  curl -XPOST http：// localhost：9200 / test / user / _search？ -d'{
query：{term：{_all：{query：Vaibhav，analyzer：
lowercase_keyword}}}}'
  

结果：

  {error：SearchPhaseExecutionException [执行阶段[查询]失败，完全失败; shardFailures 
 {[kws9J6tbQtWCMNKBm3Gpkw] [test] [4]：SearchParseException [[test] [4]：
从[-1]，size [-1]：解析失败[无法解析源
 [\\\
 {\\\
\query\：{\\\
\term\ ：{\_all\：{\query\
：\Vaibhav\，\analyzer\：\lowercase_keyword\}} \ n} \\\
}]];嵌套：
 QueryParsingException [[test] [term] query不支持[query]]; 
} {[kws9J6tbQtWCMNKBm3Gpkw] [test] [1]：SearchParseException [[test] [1]：
 from [-1]，size [-1]：Parse Failure [无法解析源
 [\\\
 {\\\
\query\ ：{\\\
\term\：{\_all\：{\query\
：\Vaibhav\ ，\analyzer\：\lowercase_keyword\}} \\\
} \\\
}]];嵌套：
 QueryParsingException [[test] [term]查询不支持[查询]]; 
} {[kws9J6tbQtWCMNKBm3Gpkw] [test] [2]：SearchParseException [[test] [2]：
 from [-1]，size [-1]：Parse Failure [无法解析源
 [\\\
 {\\\
\query\：{\\\
\term\：{\_all\：{\query\
：\Vaibhav\，\analyzer\：\lowercase_keyword\}} \\\
} \\\
}]]];嵌套：
 QueryParsingException [[test] [term]查询不支持[query]]; 
}]，状态：500} 
  

在查询弹性搜索服务器进行某些类型的查询时，我们可以定义分析器，而对于其他类型的查询，如果没有，我做错了什么？

任何帮助都非常感谢。 / p>

解决方案

术语，前缀和通配符查询期望查询中指定的值已被分析。

I am pretty new to elasticsearch and just need some clarification: Can we define a analyzer while querying the search server. I tried it with the "text" and "field" query and it works fine:

Query:

curl -XPOST http://localhost:9200/test/user/_search? -d '{ "query" : {
"text" : {"_all" : {"query" :"Vaibhav","analyzer" :
"lowercase_keyword" }} } }'

Result:

{"took":144,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":0.10848885,"hits":{"_index":"test","_type":"user","_id":"1","_score":0.10848885,
"_source" : {
   "first_name": "Vaibhav",
   "last_name":"saini",
   "password":"pwd"

But when I try to do the same thing with term/prefix/wildcard query I get the exception:

Query:

curl -XPOST http://localhost:9200/test/user/_search? -d '{
"query" : { "term" : {"_all" : {"query" :"Vaibhav","analyzer" :
"lowercase_keyword" }} } }'

Result:

{"error":"SearchPhaseExecutionException[Failed to execute phase [query], total failure; shardFailures
{[kws9J6tbQtWCMNKBm3Gpkw][test][4]: SearchParseException[[test][4]:
from[-1],size[-1]: Parse Failure [Failed to parse source
[\n{\n\"query\" : {\n\"term\" : {\"_all\" : {\"query\"
:\"Vaibhav\",\"analyzer\" : \"lowercase_keyword\" }}\n}\n}]]]; nested:
QueryParsingException[[test] [term] query does not support [query]];
}{[kws9J6tbQtWCMNKBm3Gpkw][test][1]: SearchParseException[[test][1]:

}{[kws9J6tbQtWCMNKBm3Gpkw][test][2]: SearchParseException[[test][2]:

:\"Vaibhav\",\"analyzer\" : \"lowercase_keyword\" }}\n}\n}]]]; nested:
QueryParsingException[[test] [term] query does not support [query]];
}]","status":500}

So is it like we can't define analayzers while querying the elasticsearch server for some type of queries and for others we can? If not, am I doing anything wrong?

Any help is greatly appreciated.

解决方案

The term, prefix, and wildcard queries expect the value specified in the query to be already analyzed.
