[postgis-users] Various ways to handle addresses in postgresql

[Shaozhong SHI]

Hi, Steve W,

it is easy to parse addresses as tokens.  But it is difficult to put tokens
in right columns, due to that the same address could be expressed with
partial address or full address.

The same address can be written like,  Flat 1 122 Great Avenue London UK,
or Flat 1 122 Greet Avenue Central London London United Kingdom.

When this happens, each address has different number of tokens, so
different numbers of tokens.  Is there a way to deal with this issue so
that each token can get into right column?

Please enlighten me.

Regards,

David
