</script>

Ele pesquisa de boa,mais o poblema e que quando pesquiso palavras separadas ele mostra todos os resultados em vez de 1 só

exmplo= victor e leo se eu pesquisar victor e leo ele mostrara todas as entradas que nao tem nada a ver com victor e leo,

intendem?

mesmo eu tendo uma estrada so com a palavras chave victor e leo

exemplo:

new entry ("link", "seila1", "6202, sis6202", "DRIVER PARA WIN95/98/me/linux");

new entry ("link/", "seila2", "6202, sis6202", "DRIVER PARA WIN95/98/me/linux");

new entry ("link", "victor e leo", "6202, sis6202", "DRIVER PARA WIN95/98/me/linux");

se eu pesquisar seila1 vai aparecer so o seila1,se eu digitar seila2 vai aparecer so o seila 2,se eu digitar victor e leo vai aparecer o seila1,seila2 e o victor e leo

intenderam?

tem como resolver issu?
