Hello elasticUs, I want to know which is the best route to index a text that contains codes (for example 1/56DTH) and other normal text but without losing benefits of analyzed text.  
For example I want index the text:  
"Every night I need to restart my robots 1/56DTH"

If I use an standard english analyzer (/\_analyze?analyzer=english)  
everi, night, i, need, restart, my, robot, 1, 56dth

My target is get something like:  
everi, night, i, need, restart, my, robot, 1/56dth

I think the key is create a new analyzer with a Pattern Tokenizer capable to detect 1/56DTH like a term. what do you think? I go in the correct way?
