Fewer results from a less restrictive query

[rpahut]

I have noticed that I cannot find a place sometimes unless I make the query specific enough. For example for a building:
https://nominatim.openstreetmap.org/ui/search.html?q=%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D1%8F%2C+%D1%83%D0%BB%D0%B8%D1%86%D0%B0+2-%D1%8F+%D0%AD%D0%BD%D1%82%D1%83%D0%B7%D0%B8%D0%B0%D1%81%D1%82%D0%BE%D0%B2+%2C++5+%D0%BA39&dedupe=0
nothing is found once the country name is taken out of the query:
https://nominatim.openstreetmap.org/ui/search.html?q=%D1%83%D0%BB%D0%B8%D1%86%D0%B0+2-%D1%8F+%D0%AD%D0%BD%D1%82%D1%83%D0%B7%D0%B8%D0%B0%D1%81%D1%82%D0%BE%D0%B2+%2C++5+%D0%BA39&dedupe=0

This is counterituitive, as I would expect to get at least same results from a less specific query. This is also quite misleading given that the place exists and there is nothing to the query that would exclude it from results.

Is this behavior normal? Can it be configured?
