[Package Renames] Post-MVP: Consider letting new packages match on old packages' ID

[loic-sharma]

Today a renamed package may not match the same token as the original package. Examples:

• Azure.Storage.Blobs was originally Microsoft.Azure.Storage.Blob. New package name does not match on blob queries
• Azure.Storage.Queues was originally Microsoft.Azure.Storage.Queue. New package name does not match on queue queries.

Today's work-around is to add a tag for missing tokens. We could add a new field to search documents that contains the names of the original packages. This may have the following benefits:

1. The work-around requires work from package author. Many are unaware of the work-around
2. We may be able to boost this new field better since we control it

This requires further experimentation and should be done after the minimum viable product is complete!
