Dear all,

as this is my first post, I want to thanks all elasticsearch contributors  
for this very nice tool.

However, I do not understand which analyzer is it used during the query.

The stop words seems not removed from the query for "\_al" or for a list of  
specified fields. Here is my test queries:

#!/bin/bash

#create index with specific stop words  
curl -XPOST -d '{  
"index": {  
"number\_of\_shards" : 3,  
"analysis": {  
"analyzer": {  
"english" : {  
"type":"english",  
"stopwords" : ["the", "stop1"]  
}  
}  
}  
}  
}' [http://localhost:9200/qstring](http://localhost:9200/qstring)  
echo

#apply analyzer  
curl -XPUT -d '{  
"doc" : {  
"properties" : {  
"text" : {  
"type" : "string",  
"analyzer" : "english"  
}  
}  
}  
}' [http://localhost:9200/qstring/doc/\_mapping](http://localhost:9200/qstring/doc/_mapping)  
echo

#sample data  
curl -XPOST -d '{  
"text" : "This is a test sentence containig stop words."  
}' [http://localhost:9200/qstring/doc?pretty=true](http://localhost:9200/qstring/doc?pretty=true)  
echo

#refresh for direct query  
curl -XPOST [http://localhost:9200/qstring/\_refresh](http://localhost:9200/qstring/_refresh)  
echo

#this query match as expected  
curl -d '{  
"query" : {  
"query\_string" : {  
"query" : "stop1 test",  
"default\_field": "text",  
"default\_operator": "AND"  
}  
}  
}' [http://localhost:9200/qstring/\_search?pretty=true](http://localhost:9200/qstring/_search?pretty=true)  
echo

#this does not match but why? Is it a bug?  
curl -d '{  
"query" : {  
"query\_string" : {  
"query" : "stop1 test",  
"default\_operator": "AND"  
}  
}  
}' [http://localhost:9200/qstring/\_search?pretty=true](http://localhost:9200/qstring/_search?pretty=true)  
echo

Do I miss something?

Many thanks in advance,

Regards,

-- Johnny

Hey,

you need to set the analyzer for the \_all field as well.

Hello Alex,

Thanks for your answer.

I agree that it will work on this specific case, but in my final  
application, I will use more than one term (english, french, but also  
keywords, title, etc.). In such case, I want that for a "\_all" query the  
corresponding analyzer would be used for each term, such as  
(english\_analyzer for english term, title\_analyzer for title and so on). As  
I understood, "analyzer" property is an alias for index\_analyzer and  
search\_analyzer.

I hopped that querying \_all will use the correct analyzer for each term.  
Your proposition is equivalent to set a analyzer for the query, but I do  
not want to have only one analyzer for all the terms.

Regards,
