Elascticsearch Directories ideas

Problem: With current solution, foo.{a,b}.. returns ['foo.{a,b}..a', 'foo.{a,b}..b'] instead of expanded paths

Solutions:

1. Be ok with that, but fix the post-filtering
2. Add directories (but deal with deletions, creations, inconsistencies).
3. Expand variants by hand (with should mostly work)
