The command is transaction.

...| transaction TransactionID | ...

It's quite well documented in the Search Reference manual.

UPDATE:

aholzer has an excellent point. And if that grouping is all you want to do, stats is far more efficient, e.g;

...| stats list(_time) by TransactionID | ...

Transaction is a pretty calculation intensive command to use. So make sure you read up all the different options to shrink how long transactions are kept open for.

For example, maxspan, maxwait, endswith, startswith, are all great ways to make the transaction command a lot more efficient.

yes i thought the command ...| transaction TransactionID | ... will return the correct results but it is not. If use ...TransactionID..., it will return the correct results, how come?
