In this technical story we need to come up with the syntax needed to write NOT searches, and implement this feature.
- using with control field - 001.value not= '830419m19559'
- using with subfield - 010.a not= ' 55001156/M '
- using with leader position - p_00_04 not= '01542'
- using with indicator - 240.ind2 not= '0'
- using with date in a control field - 005.date not= '20141107'
- using with position in a control field - 001.04_02 not= "89"
- Allows the user to perform NOT searches
- The requirements above are implemented
