CQRS - How to handle queries that change the system state

CQRS - How to handle queries that change the system state

I have a situation in a CQRS project where I have to log a user's request
for information (query) then optionally start a workflow based on the
response from the data store. The user is making a request for information
which requires immediate feedback. At the same time, the system optionally
starts a workflow to analyse the request. How do I implement this in CQRS
since the request is neither a 'pure' query nor a 'pure' command?
