Hi all, I think I finally found what's wrong. MapSource doesn't like the Mdr12 index which contains a few pointers with the first 4 characters of a POI name. The funny thing is that MapSource works well when this section isn't written at all. Maybe it is slower but I found no difference. The attached patch changes only the content of the section. The code now works similar to that in PrefixIndex class so that strings are compared with the collator that is set to compare only primary strength.

The uppercase.patch helps also in this case, so it is probably a good approach. Index size doesn't change with this patch, uppercase2.patch increases it. Have to analyse memory peak usage, though. @Ticker: I also tried various alternatives with Collator.setStrength() and similar but nothing fixed the search. I guess we really need a very small set of tiles with only a few strings to fully understand what's wrong.

Both attached mini-patches seem to fix the problem (but may introduce others). No idea yet if this is the right way to tackle this problem.

When I start to type that name MapSource updates the list of candidates. For scuo it shows the full name "Scuola Dell Infanzia Fondazione Pietro Caprettini" but when I select that entry with the mouse the search returns "no items found" When I type scuol the name "Scuola Dell Infanzia Fondazione Pietro Caprettini" disappears from the candidates list as well as all other names starting with "Scuola dell". My understanding is that we probably create wrong Mdr11 entries, but MdrCheck doesn't complain. The tiles are at https://files.mkgmap.org.uk/detail/536 The command to reproduce the problem: java -jar mkgmap.jar --code-page=1252 --index --gmapi 66923003.img 66923005.img 66923006.img The tiles were created with the --lower-case option and a rather special style which sometimes adds leading / trailing blanks to names. It also produces lots of equally named POI.
