Hey guys, thanks for your effort.

I've just began to work with elasticsearch since a couple of days ago and i had handled with some exceptions but one.

Anytime i try to index some files i get this exception:

org.elasticsearch.index.mapper.MapperParsingException: Failed to parse [video\_text]

I looked for some solutions on web but there is not enough topic.

Could you give me some help?
