Thanks everyone for your help by advance. I'm looking an extension Search configurable by ranking as AlibabaDotCom does.
For example: From the catalogue of products have some atribute field with a ranking: 1, 2, 3 or A,B,C so at the moment the buyer try to find some product but this same product is selling with different trademarks, so I will show in the search list the trademarks with more high ranking at the begin of the list defined by me. This way the products with high rank have more priority that others.
Thanks!
ps. I'm using Magento 2 Community Edition.
