Yes, definitely! The open source version will get all the tools and code to use the same search engine.
We still need to do some final polishing like add documentation and setup instructions before we feel confident that the released repositories will be useful for the open source version of Sharetribe. So stay tuned, this should happen during the upcoming weeks.
A small comment on your wording on “closed source Sharetribe”. We are using 100% the same code as the open source version, we just provide a hosted version where many people can create their own marketplace and receive automatic updates from the open source code. We are very committed in open sourcing everything by default if it makes sense and is useful for the community.
Thank you for your interest in the new search engine, we will announce it here in the forums when it is released!
