Witam, mam od pewnego czasu problem z wyszukiwarka, sprawdzałem ja na paru frazach i wydawało mi sie ze działała dobrze. Byłem w błedzie. Po wpisaniu frazy w wyszukiwarke nie szuka ona prawidlowo i jest to problem z zapytaniem do bazy danych, Zrobilem tak aby szukala po tytulach ale.... szuka dobrze tylko 1 słowo, po wpisaniu 2 szuka albo 1 slowo albo 2, prawdopodobnie szuka 1+2 ale nie jest to wyswietlone na samej gorze bo mam spora baze danych i jest zasypane przez inne rzeczy. Moze ktos mi pomoc?

Tak wyglada moj kod. Umieszczam całosc a nie tylko same zapytania bo moze w czyms innym tkwi problem

Może zamiast kombinować z generowaniem zapytań w PHP wykorzystasz wbudowany w MySQL mechanizm : http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html

Kolejnym dobrym rozwiązaniem jest Zendowa implementacja Lucene : http://framework.zend.com/manual/en/zend.search.lucene.html
