UPDATE

ダウン私の元の答え私はあなたがメートルを使用する必要があります奇妙な提案

を持っていますここでmyisam_ftdump

と呼ばれるYSQLユーティリティは、テキストファイルとしてこれを生成することができる場合、あなたはPHPは、あなたが探している単語のためにそれを解析持つことができ、私のオリジナルの答え

C:\MySQL_5.5.12\data\sandro>myisam_ftdump -vc txtdata 1 
     2   0.4054651 everyhing 
     2   0.4054651 impossible 
     1   1.3862944 knew 
     3   -0.4054651 know 
     2   0.4054651 nothing 
     1   1.3862944 people 
     2   0.4054651 possible 
     1   1.3862944 probable 
     1   1.3862944 something 

にサンプルからFULLTEXTダンプです。 BOOLEAN MODE付きまたはなし

ORIGINAL ANSWER

、答えはノーです。次のように

ただし、単語の出現と全体の文字列の長さに基づいてランキングを表示することができます：

サンプルデータを

DROP DATABASE sandro; 
CREATE DATABASE sandro; 
use sandro 
CREATE TABLE txtdata 
(
    id int not null auto_increment, 
    txt VARCHAR(255), 
    primary key (id), 
    FULLTEXT (txt) 
) ENGINE=MyISAM; 
INSERT INTO txtdata (txt) VALUES 
('I know Nothing is possible'), 
('We know nothing is impossible'), 
('I knew everyhing is possible'), 
('We know everyhing is possible'), 
('For may people something is probable'); 

ここでは、さまざまな検索ランキングの結果である
