Hunk - transactions support & other time ordered commands

[splunk_zen]

Hi.

http://docs.splunk.com/Documentation/Hunk/latest/Hunk/Searchavirtualindex

Explicitly states

"
The following commands are not supported when the search includes a virtual indexes:
• transactions
• localize
"

Though when I use the

| transaction fieldA startsWith=InitialKeyword endsWith=FinalKeyword keepEvicted=false 

I do get output, which is confusing as when using not supported SPL I would expect to get some kind of error.
Does that mean we just don't get guarantees the output is correct?
In that case why isn't the | transation command rather documented as:

"The following commands work on virtual indexes, but their results may differ from Splunk"

What does your full search look like? transaction requires that the events it sees be in descending time order and it should throw an error stating such - unless of course you force ordering of the events using sort as one of the commands before transaction
