Question

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]:

}]","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.

Answer 1

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