I'm wondering why words appear to entered twice in the word table, once plain and once with a leading space. This table is part of Nominatim (or Gazetteer as it was called when i first installed it). Here are links for the create table statement. |

Tokens with a leading space constitute full matches (names), while those with out spaces are simple words. To give an example: for 'swan lane rd', you will find ' swan lane rd' as the name and 'swan', 'lane' and 'rd' as partial words. Single word names have always two entries: 'london' will have ' london' for the full name and 'london' as a word match. |
Please tell us what word table you are talking about.
