Christine, you might find this blog post helpful. https://www.familysearch.org/blog/en/a-beginners-guide-to-searching-records/
I always try to add a minimal amount of information in to the search functions, unless I am researching a very common name. I try to allow the system to show me the best matches that it can. If I get too many results, I try to narrow my search down by providing additional details or requesting exact matches.
