How do Tags work on Printables.com?

I'm curious about tags on Printables and if someone can cast some light on the subject I'd love to understand the theory better!

In real life - I have just uploaded a model "Bed side table".     

I presume that the words in the title are <header> tags themselves and do not need repeating, however there may be someone searching for a "bedside table" at some point, so I add a tag "bedside".

If there's a flaw in that logic please let me know.   The thing I'm most curious about is that almost every time I go to add a tag I am offered a bunch of existing tags which are made of multiple words, in this instance "bedsidetable".

I think it's unlikely that anyone will ever search for that term, or the even less likely "phonechargerstand", and I don't think the search facility has the ability to separate those words.  My understanding is that "phone" "charger" "stand" could be found under any combination of one or all of those words.

I'd appreciate confirmation or otherwise of the above from someone who ACTUALLY knows how this works please!
