Hi all,

The current data that I am working with includes DNA\_sequence as one of its Json fields.  
Currently, I am not able to search subsequences of the DNA sequence, and I suspect es turned off analysis for this field because it was so long and void of spaces.  
How would I go about allowing subsequence searches for this field?

These subsequences should be no longer than 2000-5000 characters  
Thank you!

@polyfractal did a demo / presentation about this. You can find the slides here: [http://fr.slideshare.net/ZacharyTong/boston-meetupgoingorganic](http://fr.slideshare.net/ZacharyTong/boston-meetupgoingorganic)

I'm sure he can help here if needed 😛
