I've added a search bar to my hub site, however it looks like it searches by items that have been published. I was hoping for a search bar for my hub site, not content within ArcGIS Online. Is there a way to create a search bar that would look for words within your hub site? For example if your hub site was for an animal shelter, if a user typed in the 'dog' - all content using with the word 'dog' would be listed. Is this something that is currently available?
