🐞 Bug - Blank Search Functionality

In the search icon under blog section of navbar, the prompt suggests type and hit enter for searching. However, I noticed that even when the search bar is left blank, it still triggers a search and displays results for a blank query when press enter. Ideally, a blank search should either prompt users to enter a valid search term or should not trigger a search without any input.

Steps To Reproduce
Visit the CircuitVerse platform.
Go to blog section in navbar.
Click on search icon .
Leave the search bar blank and press enter.

Expected Behavior
A blank search should either prompt users to enter a valid search term or should not trigger a search without any input.

Device Information [optional]

• OS: Windows
• Browser: Google Chrome
• version: 120.0.6099.62

Additional context
I believe addressing this issue will enhance the overall user experience on the platform. Thank you for your time and efforts in maintaining CircuitVerse.

Start at the search icon in the blog section of the navbar and reproduce the blank-query behavior described in the issue. Trace the search entry point and ensure pressing Enter with no input does not perform a search or instead prompts for a valid term, then verify the behavior in the reported browser flow.
