_Is there a way to provide a weighting or boost value per word at the index  
or mapping level?_

I can probably accomplish this at the query level, but that could be very  
bad if I have 50 words whose impact I need to reduce.

I feel like this would be a token filter, but I can't seem to find anything  
matching. It'd be great to be able to establish a config file with a list  
of words and their boost values.

I also posted this question on stackoverflow here[http://stackoverflow.com/questions/14468221/in-elasticsearch-is-there-some-method-to-reduce-the-importance-of-a-set-of-sear](http://stackoverflow.com/questions/14468221/in-elasticsearch-is-there-some-method-to-reduce-the-importance-of-a-set-of-sear) in  
case you need some rep!
