That is correct. The project is at its early stages. I want to see what the community need the most and shape the project towards that goal. On the other hand I tried to avoid optimisations until most of functionalities are implemented.

It's a very nice idea and you should be proud of what you've built, but my personal opinion is that speed is a core feature of `grep`.

A good place to start would be this: why GNU grep is fast[1] - Starting with the Boyer-Moore string search algorithm and reading through the optimizations done in GNU grep.

p.s. there's an implementation of Boyer-Moore hiding in Go's standard library.
