I have Laravel 6.x and need an advanced search for mariaDB. I would need a search that searches all columns if they contain a specific string.
Example:
+----+-------+--------------+
| id | name | lastname |
+----+-------+--------------+
| 1 | peter | peterjackson |
+----+-------+--------------+
| 2 | petery| hans |
+----+-------+--------------+
| 3 | hans | han |
+----+-------+--------------+
| 4 | petty | bun |
+----+-------+--------------+
Search querys:
peter: 1
peters: /
pet: 1,2,3
I tried already TNT-search but it only searches if the whole string is the same. So pet would only trigger at id=2.
Example for TNT-Search (Laravel Scout):
People::search("pet")->get()
*no records*
People::search("peter")->get()
record id 1 (id 2 not included)
Algolia search isn't an option because I can't outsource data into other data-centers.

This is untested and could certainly be improved, but this should do what you want:
Add the below methods to your model, or better yet your base model which is extended by all your other models:
/**
* An array containing the names of all of this model's columns
* #var []
*/
private $_columnNames = [];
/**
* Get an array of info for the columns of the given connection and table
* #return array
*/
public function columnInfo()
{
return DB::connection($this->connection)->select(DB::raw('SHOW FULL COLUMNS FROM '.$this->table.';'));
}
/**
* Get an array of all the column names for this db model
* #return array
*/
public function getColumnNames()
{
if (!$this->_columnNames) {
$this->_columnNames = Arr::pluck($this->columnInfo(), 'Field');
}
return $this->_columnNames;
}
/**
* Get all records where any table column is like the given value
* #param string $value
* #param array $selectColumns An array of columns to return
* #return \Illuminate\Database\Query\Builder
*/
public static function whereAnyColumnLike($value, $selectColumns)
{
$queryColumns = (new self)->getColumnNames();
$selectColumns = $selectColumns ?: $queryColumns;
$query = self::select($selectColumns);
foreach($queryColumns as $key => $column) {
$function = $key === 0 ? 'where' : 'orWhere';
$query->$function($column, 'LIKE', $value);
}
return $query;
}
Then you can call SomeModel::whereAnyColumnLike('%pet%')->get();
