Search Implementation On A Website

I have a website with more than 200,000 products. I want to implement a proper search functionality. The customer on the website should be able to get the most accurate result based on his search. There are various attributes such as city, country, category etc. A sub search should also be allowed. For eg, if the user has searched for country “A” then he should be able to search further within country “A”. In the search result, categories with number of products, price range, city, country & other filters should also appear for a customer to filter further.

The search should monitor and improve continuosly.

I’m open to using any search support platform such as elasticsearch, typesense or anything else. When you quote, please share your similar work. Also, it’s upto you to setup server etc or anything needed to implement search.
