[mkgmap-dev] [Patch v1] improve mdr7 index

Wed Apr 12 22:28:52 BST 2017

Hi Carlos,

the global index is created from data in the img files. The algo has no access to the original OSM data.
If you append information in brackets () they are not indexed. Does that help?
Or maybe we can define another special character which starts information that should be ignored?

Gerd

Wouldn't it be better to compare with actual values in OSM object?
By the way, could you add capability to catch multiple words? I would
like to remove from index entries like "grade1, (3m)"
