Face the same problem you're facing. Our small team at PsyTech believes that your problem isn;t really with Search, as much with Discovery. You should be able to fetch content on a pull basis without plugging in keywords into an input box everytime.
To solve all of this, we are trying to build mutter, as a better way to curate for everyone. Please do try it out and share your [email protected], and hopefully you won't have to Search again :)
