Hello,
The Search functionality isn’t directly influenced by the Theme. The Theme uses the default WooCommerce one. So, to change the message regarding Nothing found that you are referring to, there is no option in Theme Settings available for that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.
Although, if you are keen to changing the text appearing there then you can check the following Theme file location to change that text:
wp-content/themes/woodmart/woocommerce/loop/no-products-found.php
In the above Theme file, on Line Number 17 you will find the text present. Change it according to your choice.
Remember to do the required changes under the Child Theme because if the changes are done under the Parent Theme then with the Theme Update released in future, the changes will get wiped out.
Here is the guide to set up Child Theme (if required): https://xtemos.com/docs-topic/setup-child-theme/
Best Regards
