Time to Live for data
Also nice to have feature would be to purge data which is more than x days old by issuing explicit command or having TTL on documents.
Thank you for your feedback. We’re considering this for a future release of Azure Search.

Do we have any updates on this feature ?
TTL for azure search will bring a real value add as its required in many scenarios rather than explicitly having a Purge mechanism.

@Microsoft: Under review still?
I'd like to be able to specify a low-watermark. Similar to a high-watermark that indicates what's new, but then to indicate what's obsolete. Alternatively, support eviction policies. This way my index won't fill up, I won't need to do manual cleaning, and irrelevant /obsolete search results will not appear.
Given Search is expensive would it also make sense to have a predicate that allowed certain data to be aged onto slower storage and therefore incur lower costs? Think of what SQL Server is doing with tables stretching into Azure
