Adding a database of products is a matter of creating the template using the appropriate markers that match the field names and creating a form to insert items and mark itmes as removed. Contact me for details. I use SQL, there may be import logic we can use to set up the db faster for time to marker concerns and follow up with the maintenance later.

If a database search is used I will suggeest a vector similarity approach if large or another style if smaller. But both will have natural language search and results. And may include recommendations.
