Find a Unicode text string.
BOOL pdfFind2(PDFViewerHandle viewer, wchar_t *text, int flags)
This function searches the current PDF file for a given text string. It is a more powerful version of pdfFind and pdfFindNext, adding the ability to search for a Unicode string, as well as backward and case-sensitive searching.

pdfFind2 returns a boolean, indicating whether the search string was found.

The flags argument contains zero or more of the following flags (or'ed together):

/* do a backward, case-sensitive search */ pdfFind2(viewer, L"Needle", pdfFind2Backward | pdfFind2CaseSensitive);
