I've User domain class and couple of domain classes connected by using it. I wish to have the ability to search during my domain classes, so that as result get all customers connected with keyword.

(for instance basically type "eng", it need to search in user, languages, hobbies ... domain classes fields values, and obtain all customers objects connected with individuals classes).

Who know worthwhile method for this?

I've attempted to look with searchable wordpress plugin, but it doesn't work with hbase.

I personally use grails-1.3.2 and hbase-.2.4

You'll most likely need to make your own Compass integration because the hbase plugin replaces the conventional Hibernate plugin. You can start using the Searchable plugin source code to obtain a jump.
