Search-string aware label generation

Currently labels are generated using a fixed format. Here in finland, addresses can be expressed in 2 standard ways:

name/street addr, postalcode, locality
name/street addr, postalcode, localadmin

Locality resembles the division to postal code areas and is hence quite a natural way to express a post address. Also, locality often refers to the traditional well known area name, whereas localadmin is the current administrative division, in which several localities have been joined. Spoken language often prefers locality.

Other countries may have similar conventions.

I would be a nice option if search results could use the same convention as expressed in the query. If the user searches 'Ojatie, Kuru', he probably expects to get exactly that address, not 'Ojatie, Ylöjärvi'.

The desired convention/behavior can also depend on the application using the geocoding service. Configurability will be a good way to tackle this.

No files, tests, or entry points are named. Start by locating the fixed-format label-generation and search-result formatting paths, then determine how the query’s address convention and application-specific configuration should be represented. Done means a documented, tested behavior for selecting labels such as locality versus localadmin.
