I get the following error when I try to insert a doc

_TransportError(500, u'IllegalArgumentException[TokenStream expanded to  
44800 finite strings. Only \<= 256 finite strings are supported]')_

_Index: This gets created successfully_

\*Doc to insert: \*

\*This gets inserted fine \*  
json3 = {  
"name" : "ABC 123144",  
"suggest" : {  
"input": ["ABC 123144"],  
"output": "ABC 123144",  
"payload" : {  
"id" : "ID123"  
}  
}  
}

_This doc gives the above error_

- json2 = {\*
- 

```
   "name" : "ABC 123144 ASDASD ASFSDFADF GROUP ADSAD ADAFAFAF",*

```

- 

```
   "suggest" : {*

```

- 

```
       "input": ["ABC 123144 ASDASD ASFSDFADF GROUP ADSAD ADAFAFAF"],*

```

- 

```
       "output": "ABC 123144 ASDASD ASFSDFADF GROUP ADSAD ADAFAFAF",*

```

- 

```
       "payload" : {*

```

- 

```
           "id" : "ID123"*

```

- 

```
       }*

```

- 

```
   }*

```

- }\*

What are the possible solutions or alternatives for this error ?

Thanks
