I wanted to write a quick script to remind myself of follow-up action items put on the various google documents, out of google drive to benefit from the API list(). However, it
The q parameter is very nice it lets you search for files and directories in Google drive. However it does not let you search on all of the properties of a file. As far as i know followup action items is not one of them.
Documentation
The Google docs api to my knowledge does not have a q parameter for searching the contents of a file.
Really i think that followup:actionitems
is out of scope for the Google drive api its just a file storage api it doesn't keep track of any settings you setup in the Google drive web application. as you can see from the file.resource object that isnt even a properly on a file in google drive api
