There is no way to limit your results to records with abstracts. This is a good idea, though, and we are going to work on it, especially since we are evaluating very short abstracts in terms of their helpfulness. I am looking for an article by Jose Sanchez. I found five records but none of them is the article I need. Desperately, Try checking some other forms of the name.
Authors usually use both names but occasionally use only the first.
Try typing sanchez in the author box and check the autodex. Scan all the entries beginning with Sanchez . We know this scanning takes time. You still may not find the article that you re seeking. I see typographical errors and misspellings in the autodexes and abstracts all the time.
