Historicalimages review for Shopify Search & Discovery

The good things are that this app is free but it still can be improved a lot. There are so many things missing. Being able to give weight to tags, description or title or leave them out. Include specific metafield. The worst for me is that it does not leave me to search if both tags are present ina product. Many times, products with only one of the tags present are shown. Incedible that Shopify official search is so outdated and primitive.
