 ## Conditional Blob operations with Blob Index tags
 In REST versions 2019-10-10 and higher, most [blob service APIs](https://docs.microsoft.com/rest/api/storageservices/operations-on-blobs) now support a conditional header, x-ms-if-tags, such that the operation will only succeed if the specified blob index condition is met. If the condition is not met, you will get `error 412: The condition specified using HTTP conditional header(s) is not met`.

 -	Uploading page blobs with index tags currently does not persist the tags. You must set the tags after uploading a page blob.
 -	When filtering is scoped to a single container, the @container can only be passed if all the index tags in the filter expression are equality checks (key=value). 
 -	When using the range operator with the AND condition, you can only specify the same index tag key name (Age > ‘013’ AND Age < ‘100’).

 ### Can Blob Index help me filter and query content inside my blobs? 
 No, Blob Index tags can help you find the blobs that you are looking for. If you need to search within your blobs, use Query Acceleration or Azure Search.
 
+### Are there any special considerations regarding Blob Index tag values?
+Blob Index tags only support string data types and querying returns results with lexicographical ordering. For numbers, it is recommended to zero pad the number. For date and times, it is recommended to store as an ISO 8601 compliant format.
+
 ### Are Blob Index tags and Azure Resource Manager tags related?
 No, Azure Resource Manager tags help organize control plane resources such as subscriptions, resource groups, and storage accounts. Blob Index tags provide object management and discovery on data plane resources such as blobs within a storage account.
