I found a Strange thing.
When I query a GQL like this:
"SELECT * FROM RgeoData where Y=3000"
The result of first row is like this:
ID/Name Y areaId maxX minX
130520 3000 2054 8125 8113
But when I query a GQL like this:
"SELECT * FROM RgeoData where Y=3000 order by minX"
The result of first row is like this:
ID/Name Y areaId maxX minX
130521 3000 2053 8237 8236
And I haven't found row(minX=8113) in all the result rows;
Whe is the row(minX=8113),Is this a bug?
PS:
1.This phenomenon is not accidental,It will always reappear;
2.After i upload data to system,I wrote a class to read the
data,so GAE alto create index for data ,the current index status
is :"Y ▲ , minX ▲ Serving",All OK
3.All the four fields has the same type:int
