Did you use the SELECT command? – Lior Kogan May 04 '22 at 19:10

RediSearch only works on database 0. We also consider SELECT to be an antipattern. – Simon Prickett May 04 '22 at 20:52

This is because RediSearch only operates on the default (0) database in Redis. Using numbered databases and the SELECT command is somewhat of an anti-pattern in Redis and I'd always recommend instead namespacing your keys using something like ":" as a separator or using different instances of redis-server if you have different types of data storage needs that you're currently spreading out across different numbered databases in the same redis-server instance.
