The NSI Grid | Search Filter is a powerful search and filtering system of content and metadata for any publication post found in the Publications archive. Live search and filtering are triggered when typing in the search box, clicking on the search icon, hitting the return button, or selecting a drop-down menu item, checkbox or radio button from any one of the six filters. The filter Type is a single-select filter (i.e., only one value can be selected at a time), whereas the filters Year, Author, Region, Domain and Methodology are multi-select filters (hold down the CTRL key to select multiple values). When multiple keywords are entered in the search box, OR Boolean logic is used across those keywords. Likewise, when multiple values are selected in any one of the multi-select filters, OR Boolean logic is used across those values. However, AND Boolean logic is used across the search box entry and filters when selecting values in more than one filter.
