I am not very sure if you are talking about a bit complex boolean queries.
According stardard boolean logic, complex if-else would be normalized by
using union, intersection, not.
you omited some of your logic, lets assume it as:
if( FieldA == myval1) {
if(FieldB == 1){
don't return the document;
} else {
return the document;
}
}else if(FieldA == myval2) {
if(FieldC == 1){
don't return the document;
} else {
return the document;
}
}else if(FieldA == myval3) {
if(FieldD == 1){
don't return the document;
} else {
return the document;
}
}
then you would use a boolean query as:
(FieldA:myval1 -FieldB:1) OR (FieldA:myval2 -FieldC:1) OR (FieldA:myval3
-FieldD:1)
see, this is a normalized boolean logic.
hope it helps.
