Version 5.3.0.Beta1 publishes modules under slot "5.2" as an alias to slot "5.3.0-SNAPSHOT".
Infinispan adopts the convention of hibernate search modules using slot "major.minor", so it'd be "5.3".
Might consider removing infinispan dependency from search since it still has a circular dependency in integration-tests/wildfy, that depends on infinispan modules which in turn depends on hibernate search modules.
