Change the text 'Please select at least one search

I noticed if someone does a search and there are no results, they get a message that says Please select at least one search criteria. I would like to change that message to say 'There are no results found' instead. Where can I do that?

Thanks

Try to change it in language file. There is a tool in admin panel to change any string in the component.
Just select 'Translate labels' -> Language 'en-GB' -> 'Frontend'. Use Ctrl+F to find needed string and rewrite then Save.

That's an excellent idea Anatoly. Thank you.

When I update the text and hit the save button, it's not saving. I've tried both IE and Mozilla. cleared cache.

Does anyone have any thoughts on why it won't save?

Hi Jeanette,
It seems you are using Joomla 3.x, right?
Thanks
