I need a customised version of Nominatim. This works with postgres, php, postgis and OSM. As it is released Nominatim only does whole-word searches, which is not sufficient for us. We have our own server with a medium size region installed. Also the service is installed and working. Now we need it to be adapted for our purpose. We need some to find a way of adapting the logic so that the last token is used as a partial search word. I understand this is feasible but it is best done by someone who has been involved with php based OSM processing. There is a bit of budgetary flexibility, but results are paramount.
