Please note that these are hashtags that have been used with your query word.  Stats on them give you an idea of what to expect if you use them.  The user has to determine relevance, however.

RT Team: see his No. 4 phenomenon: this is like the pre-filled tagset save box issue we have in asana.

I spoke with Kouji, main issue is that TagSets are for saving hashtags, not hashtags + text, URLs, etc.

Thanks, Kouji.  I will try to explain to the guys in the coming week.
