You can trim the input text and if trimmed text is empty string then you can show your validation message. If trimmed text is not empty string then you can allow the search to proceed with its default functionality.

From your latest reply it seems that you want to show some other message if the value entered in search box does not match any values in database. If my understanding is correct then following are the options through which you can achieve required functionality. If you are searching the resulting from database using your own logic then you can check the count of results. If the count is zero then you can show the customized message. If displaying of search results is not in your hand then you can find which controls are used for displaying the validation messages and search results. Depending on the values of these tags you can show the respective validation message. It will be good if you share few more details on your requirement.
