How to get better results from LSP?

[pintassilgo]

For instance, JavaScript. I did as inscructed here. By installing typescript and typescript-language-server, it also enabled LSP for Kate (KDE Plasma default code editor) because the editor uses this server by default when it's installed.

But, for some reason, sometimes Kate autocomplete suggestions are better than Cuda. Example:

Kate:

CudaText:

Anyone who has ever coded JS for webapp knows how often you need to use document.querySelector. On the other hand, I've never seen anyone using document.queryCommandEnabled. Instead of a purely alphabetical sorting as Cuda is doing, I want the relevance sorting as Kate does. As I said, both are using the same LSP server.

Similarly, if I type document.qs, Kate still suggests document.querySelector, while Cuda has nothing to suggest.
