Hard limit of 25

I just found that the Drupal 2.3 version has a huge problem that is affecting us too, at least my site had the problem, where only 25 users of the 3500 were returned for the user_reference I was enabling...

Confirmed! I've tested the issue with 50 referencable content items on a Backdrop demo site, and the field displayed only 25 of them as checkboxes.

It seems, in Drupal the issue is causing a lot of frustration. I hope it can be fixed for the Backdrop version of the module, e.g. by introducing a setting about the maximum number of available items. That said, there are already two different workarounds:

• Choose the "Autocomplete text field" as widget for the References field.
• Create a view with a "References" display, filter as you need, set a higher number of "Items to display", and choose this view in the "Global settings" of the field, section "Views - Nodes that can be referenced".

Btw, Entity Reference in Backdrop core doesn't seem to have the issue.

I am not noticing any discernable slow down after applying the patch (removing the limit), but the ssd-nodes VPS is grunty. YMMV especially with shared hosting.

I just hit this problem. It is located in the node_reference_potential_references function in node_reference.module and the user_reference_potential_references in user_reference.module. I guess this is to avoid performance problems. Maybe this could be a config setting of the module...
