Typo in FT.CREATE command (SEPARATOR vs SEPERATOR)

The keyword for separator is SEPARATOR rather than SEPERATOR.

Expected Behavior

https://redis.io/docs/latest/commands/ft.create/

SEPARATOR {sep} for TAG attributes, indicates how the text contained in the attribute is to be split into individual tags. The default is ,. The value must be a single character.

Current Behavior

go-redis/search_commands.go

Lines 1006 to 1008 in ad131f4

    
           if schema.Seperator != "" { 
        
           	args = append(args, "SEPERATOR", schema.Seperator) 
        
           }

Possible Solution

Fix the typo from SEPERATOR to SEPERATOR.

This issue is fixed as a part of #3132

	if schema.Seperator != "" {
	args = append(args, "SEPERATOR", schema.Seperator)
	}
