Normal usage of two 'select' generators will not do this, as they imply an AND.
A combined generator is not usable, I think, due to the different structure.
So you could use nested queries (see doc/select.html) if you need 'select' (e.g.
because you want to make a more general search over other keys too), or simply
traverse both trees one after the other (i.e. an OR).
The latter one is the simplest:
(let Text (...)
(uniq
(conc
(collect 'ttl '+Task Text)
(collect 'dsc '+Update Text Text 'tsk) ) ) )
(Not tested)
