Bill Bell commented on LUCENE-1781:
-----------------------------------

Not exactly.

testPrimeM() should be fixed by the new LLRect.java. It goes over 90 degrees, and LLRect.java pole flips. If this is not working with the new LLRect, there is something wrong with that.

testAntiM() creates a case that should fail. This condition needs to be fixed. The case is: You are located in Hawaii and you should see:

Marshall Island Airfield",7.06, 171.2
Midway Island",25.7, -171.7

It only shows the Midway Island, since it is still in the same hemisphere (it did not go from -171 to 171 (the Anti-Meridien), This case also errors since the upper right is also going over the pole. So it also is testing testPrimeM(). If we reduce the miles to 3500 it tests only these 2 points. Since it does not show Marshall Island, the Local Lucene is not working right. Once this case works people we can release it.

Here are my thoughts on a fix:

We need to get the ll to work across 180 degree point. It currently uses a straight compare, but this also needs to flip for example:  -179 + 2 = 179 longitude.
