Welcome to GPLDL - we are still beta - please report any bugs via the contact form.
However we need search capability.
If you concern about high CPU usage, you could use Google as your search engine for your site or use Elasticsearch (Elasticpress) as your search engine…
Search is finally here (in the sidebar). This is still beta but already working pretty well. Please let us know via the contact form if you experience any difficulties or strange behavior.
We hope you enjoy this feature!
