Shop search is only using the words in the title to find the product and ignoring the keywords.
If I have a listing “Under the sea” but my keywords contain: Dolphin, Beach Clipart, Summer Clipart
If I look for “dolphin” the listing does NOT get found. I have to type in what is in the title to find the product. This is a problem. When a customer is looking for something specific, they will not find it.
