Hello, I am trying to understand whether I am using the NOT operator correctly. I have the following scenario:
Query 1 = body:(a OR NOT b) This is parsed as: (body:a) -(body:b) and finds 96,620 hits Query 2 = body:(a OR (*:* AND NOT b)) This is parsed as: (body:a) (+*:* -(body:b)) and finds 149,438 hits Query 3 = body:(a AND NOT b) This is parsed as: +(body:a) -(body:b) and finds 96,620 hits Query 4 = body:(a AND (*:* AND NOT b)) This is parsed as: +(body:a) +(+*:* -(body:b)) and finds the same 96,620 hits Does anyone know the nuances when working with the NOT operator in terms of why query 1 and query 2 return different hits whereas query 3 and query 4 return the same? Is there a correct usage when you want to use NOT with AND/OR? Thanks, Ian
