Unique filter by attributes options values improve searching or filtering products. Customers are able to choose more then one value for one extra field. Filter can be used for any Oscommerce based stores (MS *, CREloaded, OscMax, WAI etc). Search help store clients to find necessary products using product attributes options values. If clients do not know name of the product but they know parameters then the search is very helpful. For example car wheels, laptops (notebooks), computers, rings, food, toys etc. Visitors who use the search can check values for only available products. Other values will be disabled. Such mechanism guarantee good search result. We use theory of combinations to develop the script and we developed unique algorithm of permutation generation which has very good speed of execution. 90% of the search results with products.
