Action:
& AND Finds only documents containing all of the specific words or phrases. For example, "Salmonella & eggs" finds documents with both the word "Salmonella" and the word "eggs". | OR Finds documents containing at least one of the specified words or phrases. For example, "Salmonella | eggs" finds documents containing either "Salmonella" or "eggs". The found documents could contain both, but do not have to. ! AND NOT Excludes documents containing the specific word or phrase. For example, "Salmonella ! eggs" finds documents containing "performance" but not containing "server". As with the & and | operators, ! must appear between two terms. [ ] Grouping Used to group portions of boolean queries together for more complicated queries. For example, "infection & [Salmonella | eggs] ! chickens" finds documents containing "infection" and either "Salmonella" or "eggs" but not "chickens".
After you perform an initial search, every matching document description will contain a "More like this" link that allows you to automatically search for similar documents.
