Refining the search for an online store. Bitrix

Smart search works incomprehensible. It does not cover the entire range of goods.

When searching with abreuatures such as "ABB," looking for everything except this model.

According to the articles also looking for others, not the one that is in particular.

We also want to set up to work on sorting - a sequence on what criterion is looking primarily for what second and so on.

Online store.
