[QGIS-Developer] Limitations of the search locator "af" option?

[Matthias Kuhn]

Hi Harrissou,

It's the "display name" configured in layer properties -> display.
What's shown in the form view of the attribute table.

This way it's highly configurable, what's actually searched for in all
the layers. Especially with numbers it would often be impossible to find
something useful without somehow limiting the attributes which are being
searched.

Regards

Matthias
