Feature proposal: Additional where equal value for each column or relation

[putchi]

Feature proposal:

In addition to the all "LIKE" queries generated and searched by relevance (thumbs up!) it will be very good to add a "or equal" query for the column or relation.

something like:

foreach ($this->getColumns() as $column => $relevance) {
$query->orWhere($column, '=', $this->search_value);
}

@nicolaslopezj what do you think? could it be done?
