We have made enhancements to how media is used in search to find relevant products:

• Minimum image dimensions: You can now set a minimum width and/or height in Search Behavior to control which images are eligible for search indexing.
• “All” image source option: A new All option allows you to include every product, variant, and media metafield image in search.
• Automatic low-quality image filtering: The system now automatically detects and excludes solid-color swatches and images with fewer than 100 unique colors. If you’d like to adjust this threshold, please contact support.
