Filter three digit bus numbers in overpass turbo

Help and support
1

Hello,
I’m currently using the following query to find all bus routes in an area

relation["type"="route"]["route"="bus"]

However I only want to match lines with one or two digits in their line name, for example

Bus 11: Nikolaus-Matthiesen-Straße => Twedter Plack
Bus 5 A: Flensburg ZOB => Campus => Hesttoft => ZOB
Bus 2 Abendlinie: Flensburg ZOB => Harrisleer Kreuz => Kupfermühle/Grenze

but not the following

Bus 130: Flensburg => Großenwiehe => Joldelund => Bredstedt

How would I be able to do this?

You can filter them by their ref tag using some regex. In your case rel[type=route][route=bus][ref~"^[1-9]{1}[0-9]?$"] should work for getting one and two digits bus routes.
