Exactly. Because of that NumberTools is deprecated as a warning, not to use it for *new* developments. The numeric values are stored completely different and can only be queried using NumericRangeQuery. These deprecations needed for index compatibility are *not* removed in 3.0 (they are targeted for 4.0, when indexes < 3.0 cannot be read anymore). So for performance reasons (if you do range queries on your numeric fields), you should reindex. > Whether 2.9 could able to modify\search the index created by 2.4.1? Is > backward compatibility maintained? Yes it is maintained, but you should get rid of deprecated APIs. And for the numeric case, you cannot mix old/new API on the same field. Switch to the new API in complete (reindex) or let it as it is.
