actually we use "aas" or "aav" for the equivalent function in tracker
simply because the hashtable/dict screws up the rank ordering
in fact never use a{xx} for anything where you want to preserve the
order of results
Well, using a flat list would require that the hit_id was a property
too. It doesn't feel right to me...
Is it really that bad to screw up ordering? There could just be a
property to sort after. If you request (0,100) you know you are only
going to sort 100 hits at a time... I acknowledge that it is doulbe
work though.
its not that - it simply passes the problem onto the client to sort
stuff which also means you need to send the rank down. Clients sould be
able to interface with the minimal amount of code.
a{xx} is only useful if you want quick random access to elements and
dont care about order.
"aas" or "aav" is no different if all the client does is iterate over
them (which almost all of them will do) especially when the backend
sorts the results, a{xx} jumbles them up and then the client resorts
them by putting them into a list - would it not be best to simply return
a sorted list?
