When a customer searches for a product in your store, a product's name, model-number, manufacturer's name, meta-tags and (if requested) description are all searched for the customer-specified keywords. If a match is found in any of those areas, the product's information is displayed.
But wait … if a product's name matched, shouldn't it be given more consideration and displayed first in the list? That's what this plugin does; it gives higher "weight" to products whose name matches the search criteria and causes them to display first.
Note: Since this plugin makes use of the Zen Cart auto-loaded observers feature which was introduced in v1.5.3, your store must be running on Zen Cart v1.5.3 or later for the plugin to operate.
