+Updating the Database
+---------------------

   With Memex Explorer you can create, run, and analyze `Nutch <http://nutch.apache.org/>`_ and `ACHE <https://github.com/ViDA-NYU/ache>`_ crawls. The crawl operation is heavily abstracted and simplified. Users provide a list of seed URLs to start the crawl, and in the case of ACHE's targeted crawling, a `machine learning model <https://github.com/ViDA-NYU/ache#build-a-model-for-aches-page-classifier>`_ to determine the relevancy of crawled pages.
