@chanuri cs , I have received an update from our product engineering team now. Apologies for the delay.
We don’t have an ETA for supporting synonym maps as part of suggesters. It is a capability that our team plans to add in the future.
As a workaround, you could upload the synonyms to the document in the search index itself, similar to what is described in this SO response: Azure cognitive search suggestion ignoring word order
Thanks again for your valuable feedback.
