It is _very hard_ as someone who doesn't specialize in this to create data that is indistinguishable based on a single search term.
It can include, for example:
* What IP addresses you are coming from
* Your username/account/email address (more on this in a moment)
* The content, frequency, or timing of your reports
* The region/datacenter you are connected to or your data is stored in.
