My site has now just under 1000 posts of maybe 400 words of text each, and ANY search takes 20 sec or more...(!) :-(
I have made all speed adjustments suggested on the settings page (such as limited to 100 posts).
I wonder how much bigger sites like Amazon etc achieve good search speeds. - Is there any chance you can significantly speed up the plugin?
(Because otherwise, to my deepest regret, I have to disable the plugin ... that I have praised so much on my site(!) - Now, the praise just makes it embarassing, really.)
