Some feedback:

Some searches, like 'deep learning', 'venture capital', and 'NLP' don't display any results. Not sure if this is a problem with the search functionality or with your database (probably the former). Some searches display a lack of context - for example, searching 'AI' returns a top result of "Air travelers" because the string "ai" is in "air".

You might consider checking out a product like Algolia to scale your search.

Awesome concept though! Excited to see it grow
