> The advance() function in the class Lucene90VectorReader does a linear search
> for the target document.
> To make it faster we can do a binary search over the "ordToDoc" array which
> will make the advance operation take logarithmic time to search.This will
> make retrieving vectors for a sparse set of documents efficient.
