Hello all

I have to index a cluster of html pages, and I want to know if:

1. Is there a direct mean with es that allows to escape html tags/special  
characters on the indexation or after search. Or do I have to escape them  
in my side?

2. since my html pages are in different languages, is it possible to use a  
different stemmer in the indexation according to the language of each page?

I am using the http api!

Thank you all

What do you mean by escape them? Do you mean strip them?
