Forum OpenACS Q&A: Re: Problems with Search installation (postgres + tsearch2)

Yes, it is included in oacs-5-2. For the bindings, go to http://yourdomain/acs-service-contract/ or "control panel -> service contracts (pages)". Check "Valid uninstalled bindings" if it is the binding is not already activated. You should also need the FtsContentProvider bindings but those are activated by default upon package installation (for example, forums, file-storage, etc).
