I have an setup with aliases like that:
If I use 2009/_search or 2009_12/_search i get all documents.
if I use test_de_2009/_search i get only the documents on a filtered field "name". I have the same filtered function with test-index_de_2009 and the "name" field, but i get no results when i search with test-index_de_2009/_search.
Whats the reason? I think its the hyphen, but i dont know why this happen and how to fix it.
