Boolean operators in NVIVO 12: what does each actually mean?

Recommended Posts

Hi,

 

I haven't been able to find information regarding the operators that are available in the Matrix Coding Query:

1. AND: Does this operator mean any degree of overlap between references? (if so, how much? down to the character level?) Or does it look only for complete overlap between references? (i.e., identical references coded by the different nodes in the query).

2. OR: Does this operator mean references of all nodes in the query? Or does it means something else?

 

3.  NOT: Does this operator mean Node A (row) fnot coded by Node B (column)? (in the sense of no overlap at all or no identical overlap?)

4. NEAR: How near is near?

5. Surrounding: what does this mean exactly? What is the exact measure here? Right before and right after a particular selection? A character before and a character after (with no overlap)? Does it have to be before and after? How far can it go before and after? If surrounding can mean references farther than a character away from other references, how far?

6.  Preceding: Again, what does this mean exactly?

 

Furthermore, in the Coding Query, what do the following options mean? "All Selected Codes or Cases" (does this mean AND?), "Any Selected Code or Case" (does this mean OR?)

 

Thank you,

 

Amir
