Wildcard indexes in Azure Cosmos DB’s API for MongoDB

In our most recent service update, we released [wildcard indexes](https://docs.microsoft.com/azure/cosmos-db/mongodb-indexing) in Azure Cosmos DB’s API for MongoDB, a popular MongoDB feature introduced in MongoDB version 4.2\. Now in general availability, wildcard indexes allow you to support efficient queries even if you don’t know all the fields needed to index in advance. Using wildcard indexes offers a simpler approach, allowing you to also index every field easily without defining each index individually. * Azure Cosmos DB * Features * [ Azure Cosmos DB](https://azure.microsoft.com/en-gb/products/cosmos-db/)
