Ok, a bit of a CS question here (I've been scratching my head for a while):

I have a sizeable array of segments (> 100K), each element basically has a length of about 100-1000 and a start/end value anywhere between 1 and a few hundred million.

I would like to be able to quickly retrieve a list of segments that fall within a specified range. so $some_tree_like_structre->get_range(50000, 1000000); would produce a list of elements which have end position >= 50000 and start position <= 1000000.

I've generally confused myself trying to google for this last night - (B|R|KD|BSP|H|P)[+-*] trees all sound fun, but I am not sure what would help me here.

A shove in the right direction would be greatly appreciated here (I am not looking for code, just need a place to start).

Thanks
