When retrieving documents in the mongo shell using the
find() method, without assigning to a var, it will print only the first 20 documents that match the query.
After which you’ll get the infamous prompt:
Type "it" for more
to iterate 20 more documents.
It can be extremely useful to increase the default number of displayed documents.
To achieve that, all you need to do is to set
DBQuery.shellBatchSize = 100;
and voilà, you now have 100 documents returned.
