Acom is going to come here and say they are no longer supporting or updating Old Search. Which is fine. But what is not fine is that they gutted some of the functionality of OS presumably in an effort to induce customers to go ahead and switch to NS.
As an example, in OS in the *Family Trees tab*, they removed the ability to add a spouse or parents as part of an advanced search. Now note the following: yes you can still have those search parameters in OS on the *historical records* tab. But *not* in the family trees tab. However one used to be able to do that.
But the overall point of this thread is that Acom has tinkered with the exact search algorithm in OS *after* foisting new search on the masses and in a manner that does not produce a truly exact search. But I predict that they will come here and try to say that one "should" be searching such and such a way, which is arrogant beyond belief since the cubicle clone product managers do not have a good grasp of genealogy search methodology.
Exact search means exact in all ways. Period. Even if it has (in the opinions of those pushing NS) some unintended bad consequences.
