Hi,

Can I used analysed fields with term filter or only non-analysed?

Best Regards,

David.

_Simple Answer_

For a term filter to drive correct results the field usually needs to be  
non-analyzed.

_Full Answer_

If you use a term filter on an analyzed field you would have to make sure  
that you provide a correctly analyzed term to the filter. This can sometimes  
make sense for fields that use a special analyzer that does not really do  
language processing. For example, you could have an analyzer that simply  
lowercases everything. You should be able to use a term filter on such a  
field provided you would do the lowercasing of the filter term on your side.
