Advanced Search Tool
General

Advanced Search lets you perform searches using Boolean logic. This function requires a basic understanding of the query-building principles.

Note: This tool does NOT ADD to the original keyword search. It is an independent search function.
Running a Single Query
  1. Click the “Advanced Search” link under the Search bar. This will disable the Search bar and open the Query Builder.

Running Additional Queries and Subqueries

After building an initial query, add another query or a subquery to further refine a search using one of two methods:

  • Add a query to the initial query to refine the search by selecting an option from the Boolean Combinator (“AND” or “OR”).
  • Add a subquery to perform an additional logical function within the initial query.
  1. Select either “AND” or “OR” from the Boolean Combinator dropdown. “AND” narrows a search based on the selected queries. “OR” broadens a search.
  2. Click “+Add Query” to add another query to your initial query. Then, repeat the previous steps to build your additional query.

  3. Click “+Add Subquery” to add a subquery to an initial or subsequent queries. Since the options for building subqueries are the same as those for building queries, follow the initial query-building steps to build a subquery.

Note: To clear a query, press “Clear Query”. Then, click “Apply Query” to reset the search results.
