Ajutor : Motor de cautare

Incerc sa realizez urmatorul motor de cautare.Problema e urmatoarea : imi genereaza linkul de search si pur si simplu face redirectionare catre pagina cautare.html fara a face vreo sortare.Intrebarea este daca imi trebuie vreo baza de date pentru acest script si daca da :cum o fac.
Multumesc anticipat!
