Subject Re: Continuous crawling

Hi Florian,

What you are seeing is "dynamic crawling" behavior.  The time between
refetches of a document is based on the history of fetches of that
document.  The recrawl interval is the initial time between document
fetches, but if a document does not change, the interval for the document
increases according to a formula.

I would need to look at the code to be able to give you the precise
formula, but if you need a limit on the amount of time between document
fetch attempts, I suggest you create a ticket and I will look into adding
that as a feature.
