By using search categories (currently available on the Home page, Local History Index and IWRDB -- The International Wine Research Database) is that you can use Boolean search logic to build complex, combined searches when multiple controlled vocabulary groups are configured in this way. While multiple terms within a single category are run as an OR search, searches constructed using multiple, different categories performs an AND search between categories.

Please Note: if multiple terms are selected from multiple categories to run a combined search, results returned will include hits found across records where at least one term from each category selected appear in the same record. In the example below, if you were to select two document types (say, Printed Book and Manuscript) and combine that with two selections from People (Charles Dickens and Jane Austen), results returned could have any of the following combinations:

• Printed Book and Charles Dickens
• Printed Book and Jane Austen
• Manuscript and Charles Dickens
• Manuscript and Jane Austen
• Printed Book and Charles Dickens and Jane Austen
• Manuscript and Charles Dickens and Jane Austen
• Printed Book and Manuscript and Charles Dickens
• Printed Book and Manuscript and Jane Austen
•  

Each term or ‘category’ will appear as an input box. Clicking on the box brings up an alphabetized list of all terms in that category – if there are over 200 terms, the list will be broken into alphabetical tabs. Where there are more than 200 terms, any terms that begin with a numerical or special character are displayed in a dedicated “#” tab that appears after “Z.” You can then browse the list or search for a specific term in the search box provided. You can select multiple terms per category.

Clicking anywhere outside the selection box will close the box and you can now click on the Search button.

Each time a category is updated with selected terms, the total number of results will be shown next to the search button so that, before you run the search, you can see if your combination of search terms will return any results.
