Advanced searches
You can perform more advanced queries using search operators.
The following search operators are available:
| Operator | Description |
|---|---|
| AND | Finds records containing both the search terms, so steel AND alloy returns only records containing both the words steel and alloy |
| OR | Finds records containing either search term, so steel OR alloy returns all records that contain steel, alloy, or both |
| NOT | Finds records containing the first search term, but not the second, so steel NOT alloy returns only records with the word steel but without the word alloy |
| Phrase Search | Finds the exact search term, so "steel alloy" will return only records containing the exact phrase steel alloy |
| Parentheses | Used to group search terms, so iron AND (ore OR cast) will return the records containing iron and containing either ore, cast, or both |
| Wildcards | Use ? as a wildcard single character, or * as a wildcard representing any number of characters (these cannot be used as the first character in a search string) |
Note: AND operators are automatically added when a search has two
or more terms and no other operators have been entered.
