$ mongo
> show dbs #optional
> use edxapp
> show collections #optional
> db.modulestore.find({'_id.category':'html'}).snapshot().forEach( function (e) {
  e.definition.data.data = e.definition.data.data.replace(/http\:\/\/docs\.google\.com/g, '//docs.google.com');
  db.modulestore.save(e);
})

# A more complex replace
> db.modulestore
    .find({
      '_id.category':'problem',
      'metadata.display_name':'Text Input'
    
    })
    .snapshot()
    .forEach(function (e) {
      if (e.definition.data.data) {
        e.definition.data.data = e.definition.data.data.replace(/stringresponse answer="\."/g, 'stringresponse answer=".+"');
      }
      if (e.metadata.markdown) {
        e.metadata.markdown = e.metadata.markdown.replace(/stringresponse answer="\."/g, 'stringresponse answer=".+"');
      }
      db.modulestore.save(e);
