One of the best things about JAMSTACK is that it is possible to provide searching the entire site with the search processing done entirely on the client. This is a big deal as there is no need for expensive servers to drive the search and more importantly it provides milliseconds latency for the users so they love to stay on the website for longer and explore.
Text search is an important part of data analysis and being able to do it entirely on the client is possible by projects like lunr. SQL Frames has integrated text search (thank you lunr). Use cases with examples are discussed below.
