(
bug 5552) add a fulltext-only search mode to inputbox
Reuse getSearchForm() for both 'search' and 'fulltext' type, IMO it should also be used for 'search2' (exact-match only), but since 'search2' is kindof strange and ignores some params (like 'break') for which I'm not sure if it's bug or feature, leaving 'search2' as separate function.
