From 8d71420b4511fdac63c39f33d93c7add1ea7716d Mon Sep 17 00:00:00 2001

Subject: [PATCH] [mod] separate index and search routes

This makes it easier to separately handle search and index requests
from a web server or from a reverse proxy.

If a request to index contains a query, a permanent redirect HTTP response
is returned. This should give some level of backwards compatibility
for users that have set a searx instance in their browser's search bar.
