when i build index for my data, a field not analyzed got this problem,who's length is too long?  
i fix it with ignore\_above but not seems better,the issue append again!  
this is my index mapping:  
.startObject("REGIONS")  
.field("type","string")  
.field("store","yes")  
.field("index","not\_analyzed")  
.field("ignore\_above","100000")  
.endObject()  
the exception like this:

You are hitting Lucene’s term byte-length limit of 32766 for this field. Note that the 32766 is a **byte-length** limit, while `ignore_above` setting is a character count limit. This is an important distinction because depending on your text, you may require multiple bytes to store a single character.

So you should really set `ignore_above` much lower, I'd suggest a realistic character count that will stop the extreme cases from being indexed. However, you may be better off just setting `index: no` for this field, so it is not searchable at all (but can be retrieved in the results).
