[PHP] Fulltext vyhľadávanie prosím o pomoc

Majo053

Ahojte velmi by som potreboval upravit nasledujuci skript tak, aby mi vyhladaval nasledovne:

Ak zadam hladany vyraz "vseobecne pravo na slovensku" tak mi tento skript zobrazi vysledok ale ak zadam "vseobecne pravo v rakusku" teda vynecham "na slovensku" a dam "v rakusku" co nemam na stranke tak mi uz nezobrazi hladany vyraz aj ked ho mam na stranke (to "vseobecne pravo na slovensku"). Chcem aby nezavisle hladal slova a nie slovo za slovom a pokial nenajde suvis s prvym a druhym tak sa skonci

. Potreboval by som fulltext vyhladavanie. Da sa to nejak spravit?

Dakujem pekne ak by sa niekto nasiel
