Use API to export search results to a PST

Can you use the API to run a search and export the results into a PST file?

I would like to write a python script to query the Archive Manager (retrieve a saved search, modify the start/end dates and email address then run the search). When the search completes I would want to export the results as a PST file. 

Can you do that, and if so, any hints as to how, would be a great help. I can't believe I am the only user who needs to do this.  I need this for electronic discovery for  our organization.

Thanks for any help you can give me.
