All versions should be possible. My recommendation is to generalize the
names before indexing AND searching. Typical patterns defined by regular
expressions should be mapped to the same strings:

- strip off all characters except letters, numbers and dots
- make the whole string lowercase
- Apply the regular expression replacements, examples:
  * "street", "str\.?", "stra(ss)|(ß)e" -> "str"
  * "rd\.?", "road" -> rd
  * ...
