I mean they're not orthogonal with respect to each other (in the
current implementation). That is:
If you turn on word or symbol search, it turns off regexp searching
and char folding.
If you turn on char folding, it turns off regexp, word and symbol searching.
If you turn on regexp, it turns off char-folding, and word and symbol
and searching.

This is not a fundamental limitation, they're not different values of
the same option. This is a consequence of the current implementation.
