How to access remote index in search_api? I have two drupal installations, one instance contains data like entities. The other one access this entities with service-calls and display the website.

I would like to make the entities searchable for users with search_api(_solr) and created an index in the data server which contains the entities.

Now.. How can I access this index from the other drupal installation? I found the services_search_api module, but there is only a DEV Version :-(

Thank you in advance for your help.
Using the services_search_api Module is the right way, but you have to apply patches from the following Issues:


Support keys: provide Key Field for searching Solr Indexes. See Comment #1
Undefined functions: add required functions from previous Services Module. See Comment #4
