I'm new to search libraries (frameworks?) but have been looking for something to use for a huge data dump I'm working with. Storing everything in memory seems fast, but seems like it'd be quite the resource hog on a server -- is that a normal approach to take? It's reassuring that the examples and documentation all revolve around books (as my data set is actually ~55 million books also), but since theirs seems to be quite the subset of that I worry about how well this scales and I don't know enough about search libs to even evaluate that. Is there a good place to start learning about what kinds of situations Typesense works best in (besides needing a Levenshtein-based search), versus what kinds of situations it wouldn't work well in (and perhaps what other libraries would work better)?
