Here you can define how a set will be build (what records will belong to this set) by defining mappings. Mappings are a list of conditions on record content. A record only need to match one condition to belong to the set.
To delete a condition, just leave at least one of 'Field', 'Subfield' or 'Value' empty and click on 'Save'.
Note: Actually, a condition is true if value in the corresponding subfield
is strictly equal to what is defined if 'Value'. A record having
999$9 = 'XXX YYY' will not belong to a set where condition is
999$9 = 'XXX'.
And it is case sensitive : a record having 999$9 = 'xxx' will not belong
to a set where condition is 999$9 = 'XXX'.
