Hey @cirdec2 sorry to hear that.
We do have various mechanisms to help make our plugin quick (it works fast for most of our users) but I’m guessing with your configuration something was happening that our plugin couldn’t handle which is having a knock on effect in terms of speed.
As a rough estimate our plugin should be quick searching a few thousand posts out of the box, and has been known to handle tens of thousands with the right configuration and server, although those numbers are probably pushing it a bit.
If you’d like us to look into it (and haven’t already done so) please open a ticket via your account and we’ll try to figure out what the issue is.
It is possible though that due to a specific combination of plugins/theme/hosting etc that we might not be able to achieve the results that we would like in your setup, but we’ll try out best.
Thanks for taking the time to share your experience.
