commit c0aa1401c455c3dd29f547eb9d8246c6df0e3a8e
Author: Ruslan Zakirov <ruz at bestpractical.com>

    Add inndexes (Local{Base, Target}, Type) instead of Links4
    
    Indexes starting from Local* columns are more selective.
    
    There were no index starting from LocalTarget. Now if you know
    local target ID then search would be very fast.
    
    Index starting from Type or having only Type column doesn't seems
    to be very selective and required.
