Index labels and examples of an expert search in Ebooks

  • You may type an index label with your search terms rather than a selection from the list of indexes to search on any search screen. The information you type overrides all default menu selections.
  • Use a colon after an index label (as in au:wang) when you are not certain of your search terms.
  • Use an equal sign after an index label (as in au=saint-arroman, august) for an exact match search.

The following may be sample rather than actual searches.
