Adding delay

[Jumitti]

FIX previous PR: int to float (my bad)

Sometime, servers where we can do requests have limit of requests per second. So adding a delay avoids this problem.

I saw in the package that there is a :param delay. Maybe you're already working on it.

This addition of delay is due to the fact that I use an API where we have an easily reachable limit. Usually 0.25 seconds is enough

Hey, does this have any advantages over adding a delay to the actual search function or adding some other logic to limit requests? Adding the delay at this level would cause a delayed load of the whole component and the page aswell.
