Ceci est la table.

Cette requête fonctionne comme prévu, ce qui donne un résultat.

SELECT * FROM posts WHERE MATCH(post_title, post_domain, post_url, post_content, post_tags) AGAINST ('%26upsilon%3B+%26alpha' IN BOOLEAN MODE) 

Alors que celui-ci ne renvoie rien d'autre qu'un ensemble de résultats vide.

SELECT * FROM posts WHERE MATCH(post_title, post_domain, post_url, post_content, post_tags) AGAINST ('%CE%B5%CF%81%CF%89%CF%84%CE%AE%CF%83%CE%B5%CE%B9%CF%82%2C' IN BOOLEAN MODE) 

Je suis déconcerté parce qu'il semble que l'inclusion d'une chaîne de caractères appropriée dans la chaîne constante pour CONTRE fait est un travail tout en utilisant uniquement une chaîne urlencoded lui-même ne fait rien.

Quelqu'un a trouvé cela?

Answer 1

http://dev.mysql.com/doc/refman/5.0/en/fulltext-natural-language.html

La mise en œuvre FULLTEXT MySQL concerne toute séquence de caractères vrais mot (lettres, chiffres et caractères de soulignement) comme un mot. Cette séquence peut aussi contenir des apostrophes ("'"), mais pas plus d'une rangée.

donc: le premier semble probablement pour « 26upsilon » & « 26alpha » (pas 2B comme elle est inférieure à la longueur minimale de mot),% s ne sont pas considérés comme faisant partie d'un mot. Votre deuxième recherche traite '%' comme un séparateur, ce qui fait que tous les 'mots' mysql reconnaissent être sous la longueur de mot minimum. Urldecode votre contenu si possible, ou utilisez LIKE pour les recherches de specifix.

Une illustration:

CREATE TABLE f (t varchar(255), FULLTEXT INDEX(t)); 
INSERT INTO f values('%foobar%fozbar%foxbar%'); 
INSERT INTO f values('%fo%fz%fb%'); 

SELECT * FROM f WHERE match(t) AGAINST ('foobar%foxbar' IN BOOLEAN MODE); 
1 Result, so % is a word delimiter 
SELECT * FROM f WHERE match(t) AGAINST ('fo%fz' IN BOOLEAN MODE); 
O results (minimum under 4 chars 
SELECT * FROM f WHERE match(t) AGAINST ('"fo%fz"' IN BOOLEAN MODE); 
O results (minimum under 4 chars) 
SELECT * FROM f WHERE match(t) AGAINST ('+fo +fz' IN BOOLEAN MODE); 
O results (still that pesky minimum)
