Thesaurus support in SQL Azure
SQL Azure do support Full Text Search but thesaurus is not included. I know few partners requesting for this feature because for their ecommerce portal they are using SQL Azure and User Search is an integral part in any ecommerce portal. They are finding it hard to design an appropriate search functionality without out of the box thesaurus support.
Incase SQL Azure team can take-up this feature that would be great.

Thesaurus is supported at this times. https://docs.microsoft.com/en-us/sql/relational-databases/search/configure-and-manage-thesaurus-files-for-full-text-search
This feature is still unavailable and would be very useful.
