Question

Answer 1

Using sorted sets (ZADD, etc) you can use ZRANK.

Edit: My old answer below doesn't work, because your list changes, although it does, with a list that only grows using RPUSH.

You could store the index with the value (or its hash) as a key:

set listvalue listindex

In order to keep your redis organised, you could prefix those keys with the listname:

set listname:listvalue listindex
