Cannot Delete Key From Redis

I’m trying to delete this key

local::1:global:queries:/search/issues?version=1.9&search=&limit=20&offset=0&category=1152:count

from my Redis database using the DEL command, but it will not delete. It just returns 0.

I’m able to delete other keys that are much simpler i.e. local::1:global:categories:1152 without a problem.

I’m trying to remove this key using the NodeJS Redis library via client.del(key)

The value of the key is very simple.
[{"count":"20"}]

    You will need to quote the key, depending on how you are deleting it.

    Via redis-cli in terminal:

    del `local::1:global:queries:/search/issues?version=1.9&search=&limit=20&offset=0&category=1152:count`

    In your case matching pattern will work due to “/search/issues?version=1.9&search=&limit=20&offset=0&category=1152”

    enter image description here

    So you can run do it through Lua scripts (redis 2.6.0^)

    here is more Information

    EVAL "return redis.call('del', unpack(redis.call('keys', KEYS[1])))"  1 local:*

    Or using bash 

    redis-cli KEYS "local:*" | xargs redis-cli DEL
