String analyzer behaves unexpectedly

I have a custom analyzer which I use on the field name. This analyzer uses standard, lowercase, stop, trim and snowball filters. The tokenizer used is standard.

I have two documents which are:

  1. Bikanervala
  2. State Bank of Bikaner

When I search for the term, 'bikaner' , shouldn't both these records match and not just the second one? Am I using the wrong analyzer?

Just test it (it= your analyzer) with:
GET my_index/_analyze?field=name
"text": [...your 2 example.s..."]

then you see exactly what you get.

I'm not 100% sure that snowball would know what to do with Bikanervala, what language is it from?
