SQL Where子句与定界符

Question

How do I write a SQL search statement where the input is a space separated string and each word belongs to a different column?

For example:

Search Input: 2011 Audi Q7

Where "2011" searches for the year,

"Audi" searches for the make,

and "Q7" searches for the model

I'm using AJAX to create a filter for my SQL table, here's the code I'm working with, but isn't working:

Database

|year|make|model|
----------------
|2017|Audi|Q7
----- ---- -----
 ... | ...| ...

PHP

public function categoryOptions() {
    $term = $this->request->input('term');
    $options = VehiclesModel::where('year', 'like', '%'.$term.'%')->where('make', 'like', '%'.$term.'%')->where('model', 'like', '%'.$term.'%')->get();
    return $options->pluck('id','year','make','model');
}

I think I need to use a delimiter in '%'.$term.'%' but not sure how thats done.

Split $term by ' ' and you will have an array with year in [0], make in [1] and model in [2]. Something like:

public function categoryOptions() {
    $term = $this->request->input('term');
    $terms = explode(' ', $term);
    $options = VehiclesModel::where('year', 'like', '%'.$terms[0].'%')->where('make', 'like', '%'.$terms[1].'%')->where('model', 'like', '%'.$terms[2].'%')->get();
    return $options->pluck('id','year','make','model');
}
