I want to pull time series data for Datastream mnemonics that match a certain criteria.
Datastream interface/desktop has categories for time series that allow you to filter your search to the relevant results. For example you can search for all time series that match: Type=Commodities, Country=USA, Activity=Dead,Settlement Date=Continuous etc. and that gives you a list of all the time series that match your criteria.
How can I do that with the Datastream API or DSWS? Is there a "search" functionality for Datastream?
I'd like for example to use ds.get_data of all the instruments that match my criteria, so I don't have to put all the names into my code manually
