Don't use prefix queries/filters

[clintongormley]

To show files by dir/ the query currently uses a prefix filter - a lot of these queries show up in the slow log

Better way to do that would be to use a path hierarchy tokenizer on that field http://www.elasticsearch.org/guide/reference/index-modules/analysis/pathhierarchy-tokenizer.html and then use the match_phrase query to search eg t/foo/bar (match_phrase to make sure they're in the right order)

You probably need something at the beginning of the path, so that you can anchor the search at the beginning as well

An alternative would be to index the dir separately from the file - probably simplest
