Among the top 3 search engine plugins

I have not tried all of them, but I have tried (for weeks) 7 of the most recommended ones.

I chose Advanced woo search for the performance, the ease of use and the possibilities it offers in terms of filters, plus the support for multi-vendor plugins (I think it is the only one).

Another item that I found super interesting and that sometimes is not valued enough, is the great level of detail of the help and documentation.
I bought the pro version and had to submit a support ticket and the response and solutions are excellent.

Another reason that made me choose this plugin is the permanent update. Something fundamental if you want to create an ecommerce.
It works very well with the woodmart theme.
