Hi Jodi,

Yes most definitely depends on your default operator.

The best way I can describe it is to think of every term having a + or – infront. Plus being AND (required), minus being OR (optional) .. if nothing, then default is used

having a default as AND:

java AND (cork OR dublin)

equals:

+java +(+cork -dublin)

so docs must have java and must have cork and may have dublin.

Very confusing.

plus, I’m querying with localsolr – I wonder if this is still an issue?

Hey Kurt -

interesting – I was not away of this – layering on my own understanding of boolean algebra

java AND (cork OR dublin)

what results would that produce? perhaps it depends on your default boolean operator? (which could be AND)

?
thank you.
