When matching address parts from addr:* tags against place names, the address names where so far converted to full names and compared those to the place names. This can become problematic with the new ICU tokenizer once we introduce creation of different variants depending on the place name context. It wouldn't be clear which variant to produce to get a match, so we would have to create all of them. To work around this issue, switch to using the partial terms for matching. This introduces a larger fuzziness between matches but that shouldn't be a problem because matching is always geographically restricted. The search terms created for address parts have a different problem: they are already created before we even know if they are going to be used. This can lead to spurious entries in the word table, which slows down searching. This problem can also be circumvented by using only partial terms for the search terms. In terms of searching that means that the address terms would not get the full-word boost, but given that the case where an address part does not exist as an OSM object should be the exception, this is likely acceptable. |
