FindAdv:

1.) Changed arrays dept and closes to vector-type because of runtime error in UserGuide.lyx
    with a big paragraph (size > 8900 chars) contained too many opening parentheses
2.) Removed one creation 'textcyrillic'-key because it is later anyway created
3.) Most important (thanks to Scott who found the failure)
    Move the check if the found string really is part of MATH to
    the relevant place.
    Without this change the search using 'Search only in maths' will fail miserably.
