Hi Thomas, the option works (and it works only if there is a mdr index), but only for street names (as documented). I don't know if it is possible to apply --split-name-index also for cities. A map without a global index might work for small areas like yours, esp. if you don't want address search.

The resulting mapset has a mdr-index file, but in (german version of) Mapsource ---> Suchen---> Orte suchen --->Stadt, it is not possible to find the city 'San Miguel de Tajao' when i only type in 'Tajao' as a part of the name. It seems for me, that the option split-name-index ist not working for the mdr-Index. The used STYLEFILE is surely not the matter. It happens with each other style. In a second test I used only options : -split-name-index but not -index . The resulting mapset has no mdr-index, but i can search with Mapsource -->Suchen--->nächstgelegene Orte suchen --> Städte, in this case it is possible, to find 'San Miguel de Tajao' when i type in 'Tajao'. In my mind this is a error. It seems for me, that option split-name-index is not working for mdr-index. Regards thomas
