How can I search several word in several fields at once? - php

Question

I am coding a search module. I do not know if I am ina good way but ti sound good for now excepted one point.
With the following code I can search only one word.
<?php
class SearchesController extends AppController{
function index(){
if($this->request->is('put') || $this->request->is('post') ){
// Save the send data
$search = $this->request->data['Search']['key'];
//$nbWords = str_word_count($search);
/*
THIS DOES NOT WORKS
if($nbWords > 1){
$searchTerms = explode(' ', $search);
$searchTermBits = array();
foreach ($searchTerms as $term) {
$term = trim($term);
if (!empty($term)) {
$searchTermBits[] = "Page.name LIKE '%$term%' AND Page.content LIKE '%$term%'";
}
}
}else{
$term = $search;
$searchTermBits[] = "Page.name LIKE '%$term%' AND Page.content LIKE '%$term%'";
}
*/
// SEARCH IN Pages TABLE
$this->loadModel('Page');
// SAVE THE RESULT IN
$d['pages'] = $this->Page->find('all', array(
'conditions' => array(
'online'=>'1',
'type'=>'page',
'created <= NOW()',
'id > 1',
'OR' => array(
//implode(' AND ', $searchTermBits)
'Page.name LIKE'=>'%'.$search.'%',
'Page.content LIKE'=>'%'.$search.'%'
)
),
'fields' => array('name','content','created','id','type')
));
//SEARCH IN Posts TABLE
$this->loadModel('Post');
$d['posts'] = $this->Post->find('all', array(
'conditions' => array(
'online'=>'1',
'type'=>'post',
'created <= NOW()',
'OR' => array(
'Post.name LIKE'=>'%'.$search.'%',
'Post.content LIKE'=>'%'.$search.'%'
)
),
'fields'=> array('name','content','created','id','type','slug')
));
// SEND THE VALUES TO THE VIEW
$this->set($d);
}else{
echo 'e';
}
}
}
The problem, I would like to be able to search with different words, for exeple "red car", "house monrain","web html5 development"
With my code, if I enter one word, it return a result, but if I add second word to the first (with a space) , it retuirn no result.
How can I change this
'OR' => array(
'Post.name LIKE'=>'%'.$search.'%',
'Post.content LIKE'=>'%'.$search.'%'
)
to make it able to search in 'name' and 'content' several words?
Thak for your help
Cheers

Answer 1

you can try this:
'OR' => array(
'Post.name' IN ('name1', 'name2'),
'Post.content' IN ('content1', 'content2')
)
Obviously you can put your value in array like this:
$name_arr = array();
$name_arr[] = 'name1';
$name_arr[] = 'name2';
and after:
'OR' => array(
'Post.name' IN ($name_arr),
'Post.content' IN ('content1', 'content2')
)

Answer 2

Change your $search variable
$search = $this->request->data['Search']['key'];
// if keywords "red car" then it will pass to your query %red%car%;
$search = str_replace(" ","%",$search);
Now it will search records having both words.

Answer 3

If you want to search with many words separated by a space, you can do this.
$searches = explode(" ", $search);
foreach ($searches as $search) {
//put your search condition in here
}

Answer 4

You might look into fulltext searching. If you setup your indices correctly, you can run queries such as:
SELECT id, MATCH (title,body) AGAINST ('Tutorial') FROM articles;
