This class can construct text search in a PDF document/an XFA document/a text page or in a PDF annotation's appearance. It offers functions to do a text search and get the searching result:
To specify the searching pattern and options, use functions TextSearch::SetPattern, TextSearch::SetStartPage (only useful for a text search in PDF document), TextSearch::SetEndPage (only useful for a text search in PDF document) and TextSearch::SetSearchFlags.
To do the searching, use function TextSearch::FindNext or TextSearch::FindPrev.
To get the searching result, use functions GetMatchXXX().
