[]
Gets the List<T> of IndexEntryOccurrence objects representing occurrences of the current index entry in the document. In the generated index, each occurrence is replaced by the page number, which is a hyperlink to the occurrence's location in the document. (Consecutive page numbers are collapsed to ranges.)
public List<IndexEntryOccurrence> Occurrences { get; }
This method always returns a non-null List<T>, creating it if it did not exist. To test whether an index entry already contains occurrences without creating the Occurrences collection, use the HasOccurrences property.
