Faster offline search by GC code
One functional way is described by mambofive here: http://help.locusmap.eu/topic/search_by_gc_code - thank God for it. But it is slow on big database. As I understand it searches whole database "brute force" on all collums. As I expect faster way would be to index the collumn "GC Code" and to implement searching by the new "GC Code" index. Or alternatively to search only the collumn "GC Code" without the index.
