Description

1. Created a tag tag1 with attributes of all data types.
2. Fired a basic search with tag1 and following tag filters of type string:
a)string != rand
b)string is not null
POST body

{  
   "excludeDeletedEntities":true,
   "entityFilters":null,
   "tagFilters":{  
      "condition":"AND",
      "criterion":[  
         {  
            "attributeName":"string",
            "operator":"neq",
            "attributeValue":"rand"
         },
         {  
            "attributeName":"string",
            "operator":"not_null",
            "attributeValue":""
         }
      ]
   },
   "attributes":null,
   "limit":25,
   "offset":0,
   "typeName":null,
   "classification":"tag1"
}

The search threw 500 Internal server exception. Attached the stack trace .

Note :
1)This exception is not seen if order is reversed (i.e) , in the order
a)string is not null
b)string != rand
In this order , correct results are fetched.

2)For string and boolean data types , this exception is seen. This was not seen with int , float, short , double , date , enum .

3)Also , this issue is seen only in tag attribute filters and not in type attribute filters.
