A Basic Search is not like a traditional Ovid search result. Multidatabase Searching Because the subjects are chosen from the OvidSP lexicon (rather than the different thesauri). They work equally across different databases. The number of results taken from each DB will be smaller because with more choices it’s easier to reach the target number of relevant records (500). Search Journals Full-Text Searching When you search full-text sources, you are searching every single word, rather than someone else’s idea of what the publication is about. Advanced search is limited to “exact match, unless truncation or synonyms are added.
