Function "->" is not returned for Clojure search

How to reproduce:

1. Go to devdocs.io
1. Enable Clojure documentation
1. Search for `->`

Expected output:

1. `->` is found

Actual result:

1. `->` is not found.

Additional info:

Seems to be specific to this particular function, as `-` `+` `->>` `-'` are returned when searched for.
