Has anyone integrated semantic + keyword hybrid search in their business?

I have an online store with about one thousand products and I noticed that the internal keyword-based search function is no longer sufficient: customers type less exact terms and either get irrelevant results or the message No results found. This generated many support tickets and a high bounce rate on the catalog page.

Two weeks ago I integrated SearchBlox Hybrid Search, which mixes semantic vector search with traditional keyword matching, and no complicated code was needed. Within a few days I saw how vague queries started delivering exactly the searched products, as if the platform understood the context.

I'm curious if you have used SearchBlox Hybrid Search or another semantic + keyword hybrid solution. How did it perform on your content volume? Did you feel it was worth the investment or did you test free alternatives?
