The IIncrementalSearch interface is associated with a ITextView.

After the Start method is called, the current caret position is marked as the start of the search. If a matching term is found, it is selected and the caret is moved to the end of the selected word.

The direction of the search is set to forward by default, although this setting can be changed with the SearchDirection property.

The AppendCharAndSearch and DeleteCharAndSearch operations can be used to change the search term.

Every search operation returns an IncrementalSearchResult, which includes information about the search, such as whether the search looped around the start or end of the buffer, whether the search looped around the starting position of the search, and whether the item was found. It is the responsibility of the caller to pass this information to the end user.

Incremental search performs its search on the text snapshot of the ITextView. As a result, if the result falls within a collapsed outlining region, the region will be expanded before the result is selected.
