In case the user doesn’t provide any input, it would be better to:

• either disable the search button

• or display a "no input - no output" message, for example:

It looks like you haven't entered anything into the search bar. Please type a keyword and try again to explore the results. 

• or display a short instruction on how to use the search func effectively, e.g.:

It seems like you haven't entered any search terms yet. 
To make the most out of Spacemesh Explorer, simply enter a transaction ID, smesher ID, account address, layer or epoch number in the search bar. This will help you quickly find the details you're looking for within the Spacemesh network.
