如何使我的SQL查询搜索句子中的多个单词，即使它们彼此不跟随

Question

I have a SQL query for my search form.

$term = $request->get('term');

$queries = Article::where('title', 'LIKE', '%' . $term . '%')->published()->get();

My research is working. If I have an article called "my great article is awesome" and that I write in my search form "greate article" it works.

But if I write "article awesome", the words do not follow each other, and it does not work.

How do I get my query to work just with keywords?

Thank you

Answer 1

You can do something like follows:

$term = $request->get('term');
$keywords = explode(" ", $term);

$article = Article::query();
foreach($keywords as $word){
    $article->orWhere('title', 'LIKE', '%'.$word.'%');
}

$articles = $article->published()->get();

If you want only results that contain all the words in the query just replace the orWhere with where .

If you want to filter out certain words you could add something like:

$filtered = ["a", "an", "the"];
$filteredKeywords = array_diff($keywords, $filtered);

Alternatively you can pass a closure if you want to be more dynamic:

$filteredKeywords = array_filter($keywords, function($word) {
    return strlen($word) > 2;
});

Answer 2

why don't you try something like that

$search = "article awesome";
$search = preg_replace("#\s+#", '%', $search);

replacing spaces with '%' will resolve the case you mentioned

Answer 3

if you want to make the search ignoring the words order this should work

$search = trim(" article awesome great ");
$search = preg_split("#\s+#", $search);
$where =  "WHERE column like '%" .  implode( "%' AND column like '%", $search ) . "%'";

however it will take more execution time and resources on the server,

also think to add some injection escaping to avoid sql syntax errors
