Do you wanna know who posted what under which tag and when and.. whatever? You can use Hyperion Zone, a very useful tool developed by @inertia.
Project Website: https://hyperion.zone
Announcement: https://peakd.com/hive-139531/@inertia/my-secret-project-hyperion
This is a main dashboard where you can sign into with your Hive account - either over Hive Signer or Keychain.
It shows that I searched dapp tag and who posted about it.
On the second image it shows that I searched for the author. In this case I used my own account and it showed me a list of posts that I recently published.
Tools is pretty good and easy to use. I recommend you to take a look at it.
