What is the error when forming a request or like?

Question

Yii

Here is the actual request

$search = Search::find()->where(['or like', ['name','description'], $query])->limit(30);

You give such an error
strpos() expects parameter 1 to be string, array given
in the documentation it is described like this

or like: Similar to the like operator, only the LIKE clauses will be combined using the OR operator if the second operand is an array.

Answer 1

"...if the SECOND operand will be represented by an array."
'or like' - operator
['name','description'] - FIRST operand
$query - SECOND operand.
Do you understand?
or like not to search for several columns. Or like in order to make two conditions in one column through OR.
In your case, you should write like this:

Search::find()->orWhere(['like', 'name', $query])->orWhere(['like', 'description', $query])
