Description
Enhancement
Now if a columnar index (vector index/inverted index) exist in a ColumnFileBig's dmfile, the index can not boost the related query performance.
In order to use the columnar index in ColumnFileBig, we can clip the result by valid packs according to the key-range of the ColumnFileBig.

Research direction
Start by locating the ColumnFileBig and DeltaVS implementations, then trace how key ranges and valid packs are handled when columnar indexes are present. Done means the relevant query path can use the index to clip results to valid packs for a ColumnFileBig; the issue provides no test or file name, so identify the applicable coverage in the surrounding code.
