This uses a headless browser (Selenium/PhantomJS) to email articles in Lexis Nexis's database about specified subjects between specified date ranges to an email address. The email is necessary because downloading files with PhantomJS is virtually impossible. This script uses parallel processing to expedite matters. Included are support scripts to download the attachments and rename them according to their contents.
Be careful when running multiple instances of this program. You may be blacklisted from Lexis Nexis. This has happened before!
I successfully ran 3 instances of this script (12 concurrent threads, given the 4 cores) without getting black listed. Your mileage may vary. Just because you're running this on a university network does NOT mean your traffic will go unnoticed by Lexis Nexis.
This was written primarily for personal use, so some conventions like line length limits are ignored.
You will need to run this on a pre-authorized network like a university connection. You may try to use your university or institution's VPN to run this at home. This program accepts input from four text files, 1.txt, 2.txt, 3.txt, and 4.txt. Format of the text files should be as follows: UnitedStates,('04/11/2002', '04/11/2002'). Essentially "countryname","tuple of date range". You will then want to download the files from the emails with dl_attachments.py and optionally rename the documents according to their contents with rename.py
