I got the the search working with Relevanssi but I think Relevanssi slows my website little bit.
Do you still prefer that I should try YITH Woocommerce Ajax Search?
My website performs pretty well on laptops.
PageSpeed Insights gives me after two tries 89-80 for laptop but 19-1 for cellphones.
Before downloading Relevanssi my site was performing as high as 93 on laptop.
I tried many different kind of JS & CSS optimizing plugins but they just broke my website.
For example I tried Jetpack Boost, Asset CleanUP and few others.
Some time ago I tested many different Cache SEO plugins and realized that LightSpeed Cache was the fastest. I have not tried WP Super Cache.
I tried also Gtranslate for easy mulitilingual app for my website and It didn’t work and then I asked Gtranslate customer service for help and they told me this:
Please contact the Basel theme developer or your cache plugin developer for further information.
