[rules-users] Question about 'query'

Hi I started to like 'query' and I think it's very useful in terms of reusing a logic. Now my question is, is it really a good idea to use 'query' as a reusable function to get a list of objects in memory or extract a value from WM? For example, I have defined a query to return the earliest date of all object X available in WM so in different rules I can get that date and use it. or another one to return a list of objects based on a criteria. What is the impact on performance? Does a query get executed each time it's invoked? or just once?
