@PublicSpi can expect
that programs compiled against a given version will remain binary compatible with later versions of the
@PublicSpi as per each product's API policy (clients should refer to each product's API policy for
the exact guarantee -- usually binary compatibility is guaranteed at least across minor versions).
@PublicSpiinterfaces and classes are specifically designed to be implemented/extended by clients. Hence, the guarantee of binary compatibility is different to that of
@PublicApielements (if an element is both
@PublicSpi, both guarantees apply).
This interface indicates the values stored in the Lucene index for this searcher are naturally ordered and as a result natural Lucene sorting can be used allowing for best sort performance.
Retrun the name of the Lucene field to use for ordering.
Retrun the name of the Lucene field to use for ordering. This will normally be just the field, .i.e customField.getId() but some searchers, e.g. TextSearcher, store additional fields to support sorting.
