Silverstripe custom search into members dataobject - search

Question

I have a little problem resolving getting SilverStripe 3.1 Fulltextsearchable running good for my usage. I retrieve some informations from Member dataobject and I create Links and Titles to show them on Page_search.ss template.
There is my code working but... bad search filtering :
public function results($data, $form){
$data = $_REQUEST;
$query = htmlspecialchars($data['Search'], ENT_QUOTES,'UTF-8');
$PageMembres = Member::get()->filter('NomOrganisme',$query);
$searchresults = new ArrayList();
foreach($PageMembres as $membre) {
if ($membre->Type==1) { $dir="repertoire-culturel/organismes-entreprises/details/"; }
if ($membre->Type==2) { $dir="repertoire-culturel/individus-artistes/details/"; }
$searchresults->push(
array( "Title" => $membre->NomOrganisme,
"link" => $membre->ID,
"Link" => Director::BaseURL().$dir.$membre->ID,
"URL" => $membre->ID,
)
);
}
if($searchresults){
$data['Results'] = $searchresults;
} else {
$data['Results'] = '';
}
$data['Title'] = 'Résultat(s) de recheche';
return $this->customise($data)->renderWith(array('Page_results','Page'));
}
So I that point, I need to change :
$PageMembres = Member::get()->filter('NomOrganisme',$query);
For a more complexe research like :
$PageMembres = DataObject::get("Member","MATCH (NomOrganisme,FirstName,Surname,Description) AGAINST ('$query' IN BOOLEAN MODE)");
What I have missed with the complexe query? Why It doesn't works?
Thanks for reply!

Answer 1

I think we can't use MATCH query on DataObject Member. There is my complexe working code that I use and works :
$PageMembres = Member::get()->where("
FirstName LIKE '%$query%' OR
Surname LIKE '%$query%' OR
Description LIKE '%$query%' OR
NomOrganisme LIKE '%$query%'");
