Elasticsearch query string query with not equal to?

Question

Usually with a query_string query in elasticsearch, I can do:

name:"Fred" 

I want to find all documents where name is not equal to Fred. What is the proper syntax for that? I tried:

name!="Fred" 

Though it returns 0 documents.

Answer 1

You need to use the NOT operator, like this:

!(name:"Fred") 

or

NOT (name:"Fred") 

Answer 2

You should use bool query with must_not statement

{   "query": {     "bool" : {       "must_not" : {         "term" : {           "name" : "Fred"         }       }     }   } }
