feat: introduce a text compress for search function

[Koooooo-7]

Summary

The search INDEX we store in localStorage, and it has the limitation about 5M. And we discussed about the Indexed DB and other solutions couple years ago. Today, a sudden inspiration struck me: instead of switching the persistence layer, we can use text compression to address our retrieval needs. So I have found some implementations of text compression algorithms，and pick the suitable one of LZW lz-string since we are more on the content/docs. Have a test based on our site docs, it reduces the 80% cost. In short term, it could be a chance for users to make search still works when their docs big but not that too much.
