Glob Patterns

[Manoj B. Narayanan]

Hi all,

I would like to retrieve the keys by pattern matching. Is it possible that in a single query I can retrieve the keys that contain any one of the words in the pattern.

Example : Keys in redis - ADE, DCR, RTY, FGH

Hoe to write a single  pattern that gives me keys containing A or R?

Thanks

Hello, blocking the server with KEYS is not recommended, however even
if you were willing to, there is no single "glob style" pattern to
match just the above strings, you can only match those strings plus
more strings, if you use, like: [ADRF][DCTG][ERYH], for example you'll
match ATE that was not your goal.
So the recommended way is to use four simultaneous iterators with
SCAN, all with a different MATCH option. Or use SCAN without MATCH and
match client-side.

Hi,

Can we write a blog pattern with OR?

Eg. Retrieve all keys containing A or B. 

Thanks.
