If text search is ever implemented, it should be limited to your home timeline/mentions only. Lack of full-text search on general content is intentional, due to negative social dynamics of it in other networks
I can't stop google from indexing public pages but there's a difference between "possible" and "convenient". There's already hashtags for when you *want* to be discovered via some keyword.
@Gargron it would be nice if it would be possible to 'follow' hashtags so they'd appear in your 'Home'. a bit like diaspora did. great way to discover content without having to manually search it out.
@Gargron I get what you mean, and I do not disagree. But whatever you choose to do, if it's "possible" we are only one-person-coding-a-script away from "convenient".
