Hi
I have further reduced the problematic map down to a tiny testcase. All that is left is:
* A single city node providing location information to mkgmap * A single road with two nodes
The road is called "Demo Street" and has a ref of "S6". If I build a map out of this data file and install it on my Vista via MapSource, search does not work. The street shows up three times in the list, as "S6 Demo Street", "Demo Street (S6)" and "S6".
Thanks for the very good example! I haven't forgotten about this although I don't have an answer. I initially believed that it was to do with the shield symbol that gets inserted before the 'S6'. This makes it sort earlier than 'Demo' if it is counted in the sort, and later if not. The purpose of the previous patch I posted was to investigate that, although when it made no difference that seemed to rule out that reason. I shall try with this test file more things with this test file.
None of this makes any sense to me. There are plenty of streets with bot a name and a ref all over the world - and these work fine. There is something very specific going on here that I do not understand.
Perhaps its because in many countries refs begin with 'A' or 'B' and so sort early anyway. (Not true in the USA though, so can't be the whole reason). It may take a while to figure it out. Thanks, ..Steve
