Search Mode
Incremental: In the first library all parts are searched, in the following ones only those parts are searched that were not found in the previous ones (default setting!).
Full: All parts are searched in each library. What happens if attributes are present on the part can be set via the setting under the respective library.
Match Mode
Complete: All parts are matched and the attributes are copied to the part.
Update: Only parts are used which have newer data than the parts on the PCB. To do this, the "LastChangeDate" of the respective package of the component is compared with that of the part found from the library.
