I want to to search C++, C# and .Net using elasticsearch

below is the query\_string method i use for searching

$keyword = "C++ C#"; //.net developer

$params['body']['query']['query\_string'] = array("query" =\>$keyword,"default\_operator" =\> "AND" ,"fields" =\> array("title","description"));

Right now if i search C++ , it only search C
