How We can do partial search in Redis using SSCAN with special characters

Question

I have created a Redis set and the following is the member of the set:

 "[test@#$demo%^here[sfs]][en-us][1234]"

I have 1000 members in the Redis set and I want to search this document using sscan partially I have tried following the way

 sscan test 0 match "[test@#$demo%^here[sfs]][en-us]"

but is not working properly So how I can do it directly without looping?

help me here to resolve this. – Suraj Dalvi Jan 14 '21 at 11:30 — Suraj Dalvi, Jan 14 '21 at 11:30

Use the \ to escape a character that has special meaning inside a match expression. You can try:

sscan test 0 match "\\[test@#$demo%^here\\[sfs]\\]\\[en-us\\]*"

Thanks, it works but is any list of special chars that I need to escape? so as per that I will update my logic – Suraj Dalvi Jan 14 '21 at 13:03
List of special chars you can check [here](https://redis.io/commands/keys) – Aleh Birulia Jan 14 '21 at 14:07
I think ., +, *, ?, ^, $, (, ), [, ], {, }, |, \ here are the list of special characters then I need to escape – Suraj Dalvi Jan 14 '21 at 17:18
any javascript function to replace all special characters with \\specialcharacter? – Suraj Dalvi Jan 14 '21 at 18:04
is ., +, *, ?, ^, $, (, ), [, ], {, }, |, \ list is valid or any other characters is present? – Suraj Dalvi Jan 14 '21 at 19:10
