Find hardware by article number, name and height

Look up hardware by its article/model number, then fall back to name and height when nothing matches.

1. For hardware such as tandem drawer systems, the article/model number is the fastest search key.

2. When an article/model number search returns no match, search again using the item's actual name; this two-step lookup works the same way for hardware and accessories.

3. If the article/model number returns no match, search by the item's name together with its height.

4. The matching sizes (for example 450, 500, 600) are then listed inside that item for selection.
