在elasticSearch中查询时定义分析器

Question

我对弹性搜索很新,只需要澄清一下:我们可以在查询搜索服务器时定义一个分析器.我用"文本"和"字段"查询尝试了它,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:

{"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"

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

查询:

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

结果:

{"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]:
from[-1],size[-1]: Parse Failure [Failed to parse source
[\n{\n\"query\" : {\n\"term\" : {\"_all\" : {\"query\"

QueryParsingException[[test] [term] query does not support [query]];
}{[kws9J6tbQtWCMNKBm3Gpkw][test][2]: SearchParseException[[test][2]:
from[-1],size[-1]: Parse Failure [Failed to parse source

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

因此,在查询弹性搜索服务器以查找某种类型的查询时,我们无法定义analayzers,而对于其他查询我们可以吗？如果没有,我做错了什么？

任何帮助是极大的赞赏.

Answer 1

的term,prefix和wildcard查询预计在查询中指定的值将已经分析.

Answer 2

这个语法对我有用:

GET /_search
{
  "query": {
    "match_phrase": {
      "controller": {
        "analyzer": "keyword",
        "query": "api/v2/test"
      }
    }
  }
}
