Diacritic Errors in Ovid
We've recently received reports of problems with results in Ovid when searching for authors with diacritics in their names. Searching by using the standard English equivalent (a for á, for example) does not retrieve the full set of results, and the use of the letter-diacritic combination either leads to no results or a syntax search error. I have replicated this issue in both Medline and PsycInfo.
I've alerted to Ovid to the problem and am awaiting a response. For the time being, using the * to replace the problematic letter seems to result in the most accurate set (compare: Fernandez$.au. retrieving 13543 results vs. Fern*ndez$.au. retrieving 38586 results).
