Precyzyjne wyszukiwanie frazy - 1.7.2.0


Crowic

Question

Witam,

 

mam problem z wyszukiwarką produktów w wersji 1.7.2.0, mianowicie kiedy chcę wyszukać nazwę produktu składającą się z 3 wyrazów np.: "Spotkanie nad morzem", wyszukuje mi również produkty które zawierają pojedynczy wyraz w swojej nazwie, czyli "spotkanie", "nad", "morzem".

 

Moje pytanie czy da się zmanipulować wyszukiwarką tak, aby przy całej frazie wyszukiwała dokładnie pojedynczy produkt, a nie całą masę?

 

Link do strony, gdzie można zauważyć problem: https://pandecor.pl

Mam ten sam problem - wyszukiwarka w tej wersji działa trochę dziwnie, zawsze znajduje mi za dużą ilość produktów. Próbowałem już ustawić wagę, tak żeby szukało tylko po nazwie produktów i nie po części słowa, ale dalej wyszukuje prawie wszystkie produkty, które mają część słowa. Oczywiście indeks cały przebudowany.

 

Przykład:

Produkt nazywa się: Dywan nr 43 oliwka 160x220cm

 

Wpisując w wyszukiwarkę znajduje mi takie produkty jak: Chodnik Dywanowy Weltom Welen Trio Stare Złoto 80cm

 

Ogólnie znajduje 1399 pozycji...

Do folderu classess wgraj oryginalny plik. Przekopiuj go następnie do folderu /override/classes  i podmień funkcje Find na:

chyba, że masz już tam taki plik (np. z jakiegoś modułu) to w tym pliku podmień.
