Search: parse address with apartment and search by at least building/street

[stragu]

Searching for "5/44 Yeronga street, Brisbane" does not return "44 Yeronga st". If a more precise apartment address does not exist, OsmAnd should still return the main address.

Looks like that address is not present correctly in OSM https://nominatim.openstreetmap.org/ui/search.html?q=5%2F44+Yeronga+street%2C+Brisbane

But 44 Yeronga st exists: https://nominatim.openstreetmap.org/ui/search.html?q=44+Yeronga+street%2C+Brisbane

The point of this report is to say that, if no precise unit/apartment address is found (e.g. unit 5, number 44, Yeronga st), OsmAnd should still return the location of the street number (i.e. number 44, Yeronga st). Just like the search still returns the suburb "Yeronga" in the search results, as shown above.

In the search process, it could look like this:

• if two numbers are separated by a / or a - (or any existing marker of a unit + street number address, like unit 5, 44 <streetname>), search for addr:unit and addr:housenumber at that street
• if no unit number matches, only search for the second number as addr:housenumber at that street.

I guess we'd have to look for what kind of convention there is in different areas (unit number usually before or after street number?), but it seems that the convention (and the most logical) is starting with the most precise (i.e. unit number) and follow with more and more general (housenumber, street, suburb, etc.)

OsmAnd also finds it but on 2nd place
