RoboMongo: Doesn't display all documents

You can change the default batch size:

• Edit robomongo.json (in ~/.config/robomongo/<version>/ on Linux/MacOS, in c:\Users\YourName\.config\<version>/ on Windows)

• Change the batchSize attribute, you can choose a value of fixed size (e.g. 100) or choose 0 to mean "all documents" (h/t to @PaulRey though I've had mixed results in using this symbolic, see comments below this question):

  {
    "batchSize" : 100,
    ...
  }
  

• Save robomongo.json and restart RoboMongo

This allows you to increase the default batch size albeit at the potential cost of waiting longer for results.

More details in the docs.

UPDATE 06 december 2019: The initial solution is not working from the v1.3.1 of Robomongo. If you enter 0, Robomongo will throw an error. See the EDIT 1 for new solution.

There is an input at the upper right which gives you the possiblity to change the number of displayed documents, just under the query. Change it to 0 and press Enter. It'll load all documents.

Even if the 50 reappears after, you have all documents displayed.

EDIT 1: The above seems to be fixed in the newer releases (from v1.3.1).

As suggested by @learnsomemore in the comments, you can add DBQuery.shellBatchSize = 500; before your query to change the returned array size.

This was originaly given in a comment by @davidm06 in the GitHub issue "Aggregate only shows 50 results #1157" from the RoboMongo public repository.

You can also use toArray() at the end to get the whole result at once.
