More Accurate Search Results
Density-based matching improves the accuracy of search results by moving products that better match search queries to the top of returned results
This is the same method of search relevence that is employed by Google .
For example, if a customer searches for "computer", then "Apple Computer" will be returned as a higher result than "Neon Blue Computer Accessory Case"
Manually Specify Weightings
Allows you to specify custom search weightings that will either reduce or increase the chances that products will appear near the top of search results.
For example, if you assign an adjustment weighting of +1 to a particular product, then that product will be more likely to appear before other products in a search (depending on the search and other product weights).
