Expert search

Use an expert search to perform a complete search in a single string. An expert search is made up of a combination of index labels and search terms. With the use of Boolean operators (AND, OR, NOT), you can search through several indexes at once and apply limits at the same time. Expert searches can be performed in the basic search area or the advanced search window.

Perform an expert search

  1. From the Data Type drop-down list, select a data type.
  2. From the Scope drop-down list, select a search scope.
  3. In the Term(s) text field, enter your expert search in this format: [Index label] [Search term(s)].
    • For example: ti: girl dragon tattoo mt:nsr pb=random house
    • When you are performing an expert search with multiple indexes:
      • The Boolean AND is implied. If you are using the Boolean operators OR or NOT, you must type the operator and use capital letters.
      • You can search using the following French Boolean operators: ET (AND), OU (OR), SAUF (NOT)
         Note: These operators must be entered in all uppercase letters to be considered Boolean operators.
