I have a wp+woocommerce and about 3 millions of products. I imported tecdata csv files for car parts. I have the ajax search pro plugin and Enfold theme. It works but searching is very slow. I am on 1and1 vps.
I need someone to speed it up. It doesn't matter if it is ajax or regular search. Searching results are important. I am also ready to change the theme if it is necessary.
