Running Azure Cognitive search over archive tier blob storage

Hi I have some containers in blob storage, a mixture of cool and archive tiers managed with Azure lifecycle management. I really want to build a search interface with Azure search across the blob storage, but the indexer won't index any blobs in the archive tier.
The documentation suggests the metadata is left online for archive blob storage - so I was hoping the search indexer would be able to use that metadata to make it's index?
What are my options / what is best practice?
thanks
Ivan

    I was able to confirm with the product team that there is currently no support for archive tier blobs with Azure Cognitive Search. I have asked that the documentation team add a note of this to avoid future confusion.

    Thanks @deherman-MSFT .
    The confusion is because the documentation states that the metadata will be left on line for discovery, when in fact the search is not able to use that metadata even if 'use storage metadata only' option is ticked.

    From what I can tell I can index the blob files whilst the files are in cool or hot tiers, then keep the index active to allow search to identify them in the index even when they have moved to archive tier. We will be using Azure lifecycle management to move from cool to archive, so all blobs will be indexable initially. If you can comment on if this approach sounds sensible that would be appreciated, thanks
