Module fire! Must have for medium and large stores with more than 10 categories. Not just as a cool feature, but really necessary. Analyzing data from google analytics, I saw that user requests are not much different from requests in Google, and with the usual opencart search in the results they get the answer - not found, because. requests are inaccurate. And if you have such a product, and the "warm" buyer did not find it, it's sooo insulting! After all, if the user is just looking, then most likely he has not decided, but if he is looking for something specific, then he is already ready to buy. This is the task of the search - to bring a buyer who is already ready to buy to your goods. And this module perfectly copes with this task! And in combination with the second module "Search suggestion - search with auto-completion PRO" it becomes even more convenient to use the search. As for the installation - a module for a standard opencart, and if something has already changed on the site, then there may be individual features. The module was easily installed, earned, but since. in my theme there were features, I had to contact the developer of the module. The developer is very responsive and immediately helped me to configure the module the way I wanted for a very adequate amount (because these are individual improvements, I had a lot of changes on the site and it's time to figure out my wilds). I am writing an adequate one, because I am well acquainted with development prices from 0. And for such functionality that the module provides, this is not a cost, but a penny! Therefore, I recommend this module to everyone! Technical support at the highest level!
