mysql search. Require all keywords

I have this sql query:

SELECT DISTINCT url FROM paragraphs WHERE 
  MATCH (title) AGAINST('$query') ORDER BY 
  MATCH (title) AGAINST('$query') DESC

What happens though is when I search, for example, for "john smith" I get "john" "john chambers" ...etc. How can I make both words requi开发者_Go百科red?

Using + in a Boolean search should make all words required:

<?php

$query = str_replace(" "," +",$query);

$sql = "SELECT DISTINCT url FROM paragraphs WHERE 
          MATCH (title) AGAINST('$query' IN BOOLEAN MODE))
          ORDER BY score DESC;"

?>

You could add an additional LIKE clause to your where to filter out all unwanted matches:

SELECT DISTINCT url FROM paragraphs WHERE 
  MATCH (title) AGAINST('$query') AND title LIKE "%$query%"
  ORDER BY MATCH (title) AGAINST('$query') DESC

Thus you have scoring and only the results matching exactly.
