Fuzzy Matching Order Notes in eCommerce with Auto-Tagging

Updated On:

,By

Shopify and WooCommerce both let customers leave order notes — but most merchants struggle to search, filter, or organize them efficiently. What if you could auto-tag notes with labels like:

  • 🎁 Gift
  • 🎂 Birthday
  • 🚨 Urgent

…even when customers write typos like “gfit” or use slang like “asap”?

Welcome to fuzzy matching — a simple way to intelligently detect keywords in messy text using native PHP or open-source libraries.


🧩 What is Fuzzy Matching?

Fuzzy matching compares two strings and checks how similar they are — even if they’re not exactly the same.

Unlike strict string matching (if ($text == "urgent")), fuzzy matching lets you catch:

  • Typos: brithdaybirthday
  • Short forms: bdaybirthday
  • Variants: giftinggift

🛠️ Use Case: Auto-Tag Orders Based on Note Content

Let’s say a customer writes:

“Please wrap this as a gfit. It’s for a brithday surprise. ASAP!”

Your app should auto-tag it as:

  • 🎁 Gift
  • 🎂 Birthday
  • 🚨 Urgent

✅ Option 1: Pure PHP (No Libraries)

You can use PHP’s native levenshtein() function — it returns the number of edits (insertions, deletions, swaps) between two strings.

🟢 Output:

Matched: gfit ≈ gift  
Matched: brithday ≈ birthday

You can tweak the $threshold to be more or less strict.


✅ Option 2: Using a Composer Library (More Accurate)

For more advanced scoring, use jfcherng/php-fuzzy-search.

🟢 Output:

Matched 'asap' ≈ 'urgent' (score: 84)
Matched 'birthday' ≈ 'birthday' (score: 100)

🧠 Bonus: Synonym Groups

Define your own keyword groups so the app can detect multiple versions of a concept.
