Search realtime incremental search

[ddaletski]

It would be nice to have a real-time incremental search like on yarn or npm packages registries. Especially when you look for some package, you don't know the exact name of.

It seems to be achievable, as yarn manages to have less than 120ms. latency of search when you type the first letter of a query (and about 5-10 ms. for consequent letters), and it has a lot more packages than there are on crates.io
