What should be query in blueprint to filter by part of field name?

I need to filter all results, that contain one certain city (city is field).

Now query in blueprint is:

query: site.find("submission").children.filterBy("workingplace", "in" , ["cityexample_one", "cityexample_two"])

As there are many working places (in same city) and we will add new, how to have query, which will filter results, if field contains “cityexample”?

Don’t use an array but the starts with operator:

query: site.find("submission").children.filterBy("workingplace", "^=" , "cityexample")

Perfect, thank you!
