Logical operators are crucial for refining search queries to meet precise needs:
- AND: The AND operator narrows the search by including only those results that match all specified criteria. This is useful when you need to find items that meet multiple conditions. For example, searching for "World War II" AND "photographs" will yield results that contain both terms.
- OR: The OR operator broadens the search to include results that match any of the specified criteria. This operator is ideal when looking for items that might fit one or another category. For instance, "letters" OR "diaries" will retrieve documents categorized under either term.
- NOT: The NOT operator excludes specific terms or categories from the search results, helping to eliminate unwanted information. For example, searching for "artifacts" NOT "replicas" will display only genuine artifacts, excluding any replicas.
* can also be used to search with cropped words, e.g. "woo*" will search wool, wood,...
