I believe that this module should be in every working store, since search is one of the most important parts of an online store. It helps managers to search for a product faster and more accurately, as well as to show users similar products if they entered a query inaccurately. We had a problem when searching by articles, for example, there is an article "sm-12222" in the standard opencart search, if you enter only part of the article 12222, then the search does not return products. This module solved this problem. And also improved and accelerated the search. The author helped to set up the module without any problems, he answers quickly. Thank him for this). I recommend to buy!
