Product Search Not Returning Results for “&”

Problem Summary:
When searching for products in WooCommerce, the search term “K&F” does not return any results, even though the product title contains “K&F” (e.g., K&F Concept Camera Backpack for Professionals Photographers (KF13.087AV2)). However, searching for “K & F” (with spaces) does return the correct product.

Expected Behavior:
Searching for “K&F” should return the relevant product, just as searching for “K & F” does.
Actual Behavior:
Searching for “K&F” returns no results.
Searching for “K & F” (with spaces) returns the correct product.
