Description

Although UIMA-2434 improved time to remove from a sorted index, removal time from bag indexes is still likely to be order(number-of-elements that are in the index), because a sequential scan is done. The ordering of elements in bag indexes is somewhat likely to ordered in ascending fs heap index order. This can be exploited to improve the performance of remove-from-index.
