Sure, but since that has nothing to do with Relevanssi itself, I’d need to see your site to be able to say anything more about this.

The site is in Russian, so in addition to the link, I will attach pictures and explanations. When searching for the word atmega, we have https://shop.fulcrum.ru/?s=atmega&post_type=product multiple pages with results. Among these products, we select products by some criterion (filter 1 or 2 or 3). Then we click the “reset filters” button and expect that the search field will also be cleared and we will see all the products, but the word atmega remains in the search field
I see you’re using Berocket’s Ajax Products Filter plugin to do the filters. The reset button comes from that plugin. Ask them, since it’s their feature they should be able to help you (or they’ll say it’s not possible). I could’ve helped with a custom homemade feature, but I won’t touch another plugin.
