infinite scroll

I am using the “infinite scroll” approach with about 25k documents, but am finding that as I slowly scroll down, it makes several ajax calls well before I get to the bottom of the list. I can stay at the top of the page, just scrolling up/down a tiny bit and it continues to make a new call on each scroll change.

I checked and in jquery.infinitescroll.js around L74 the test for scrollpositionnew >= position seems to be checking distance from the top and is always true.

The example on http://www.gotosolr.com/en/search-wpsolr/?search=*
exhibits the same behavior, just scroll a tiny bit down, then back up, then down, then up – and on each, it’ll show Loading.

note: i realize what I’m describing with up/down is not a normal behavior, but the main point is that as you scroll through a somewhat long list it pre-loads way too many documents as it’s kicking off the load more prematurely.
