The search function made possible by this extension is well suited for websites that sell items with very specific and subjective product attributes. It is especially useful to online stores, where website visitors desire an accurate search drill down process, to allow them to find the exact item they are looking for.
A good example of where this specific extension has been very helpful is for a electronic store or cloth store, but can be used in any kind of store.
