Car part number search for Shopify auto parts stores
Auto parts buyers search by the number stamped on the box, the OEM number, the supersession, or a cross-reference from another brand. Atomz writes those numbers into structured fields so your store returns the exact part instead of nothing.

Every word in the question maps to a structured attribute, so the right product is the answer.
The problem
Why keyword search misses this.
A part number is a precise string, and keyword search treats it as loose text. It splits on the dash, ignores the leading zeros, and has no idea that one number supersedes another or that a competitor's number points to the same part. So the shopper who types the number on their old part gets a no-results page, even when you stock the replacement.
What goes in, what matches
The fields that answer the search.
The left column is what a shopper types. The right is the structured field Atomz writes to your metafields, the thing search and an agent match on.

How Atomz does it
Written once, to fields you own.
Atomz reads each product and writes the manufacturer part number, the OEM number, the numbers it supersedes, and known cross-references into your Shopify metafields as exact, matchable fields. Search and the assistant then resolve any of those numbers to the one product you sell.
Everything lives in your Shopify metafields, so the same data powers your on-store search, your AI Assistant, and the off-site agents that read Shopify Catalog.
Car part number search: questions merchants ask
Can shoppers search by an OEM or competitor number, not just mine?+
Yes. Atomz writes the OEM number and known cross-references as their own fields, so a shopper who only has the number from their old part or a rival brand still lands on the right product.
What about superseded part numbers?+
Supersessions are written as a field on the current part, so when someone searches the old number, the store returns the replacement you stock.
Do I have to enter every number by hand?+
No. Atomz reads what is in your catalog and product data and writes the structured fields for you, then you review before anything publishes.
