The search operation is conducted by an ImageGear approximate regex object (HIG_REC_APPROX_REGEX) against a page (HIGEAR or HIG_REC_IMAGE), a document (HMIGEAR or HIG_REC_DOCUMENT), or a Unicode string (LPAT_WCHAR) to produce an array of matches (AT_REC_MATCH_RESULT).

To search a page, document, or string:

1. Create an approximate regex object.
2. Configure the search.
3. Search for matches.
