For my particular searches, broad matches are what is needed since there are many ways to search for what I do. Broad matches are the only way that will work for me. As it is now, I would need to do the following:
California grape grower
California grape builder
California grape constructer
California orange grower
California orange builder
California orange constructer
California pizza grower
California pizza builder
California pizza constructer
and on and on and on.
You can see the space and time this would take if there were 20 items.
But, if there were positive keywords I could do the following in much less time and space:
California grower
California builder
California constructer
+grape
+orange
+pizza
+ avacado
+ peaches
+ whatever
Then, one of those words must be in the search.
This would save a LOT of time and space for me if it were implemented.
