Because of the preponderance of Smiths I wanted to cut down the hundreds listed as possibilities. My aunt was never married, plus died in her early twenties. On impulse I listed "none" in the space for names of a spouse on Family Search field boxes. It cut almost 75% of the listings I was getting. I can't say this will always work because it is a VERY SMALL STUDY (ONE). If it helps someone else cut out useless information, I have accomplished my goal.
