I use SilverStripe 3.x. and I need to make some changes in SearchForm class - e.g. modify search results page length.
How can I do it?

The following code in mysite/code/MySearchForm.php file
unfortunately doesn't work :-(

class MySearchForm extends SearchForm {
   protected $pageLength = 100;

You can override the default search form by copying the form from ContentControllerSearchExtension to your Page class then alter it as you need.

class Page_Controller extends ContentController {
   public function SearchForm() {
      $searchText = _t('SearchForm.SEARCH', 'Search');

      if($this->owner->request && $this->owner->request->getVar('Search')) {
         $searchText = $this->owner->request->getVar('Search');

      $fields = new FieldList(
         new TextField('Search', false, $searchText)
      $actions = new FieldList(
         new FormAction('results', _t('SearchForm.GO', 'Go'))
      $form = new SearchForm($this->owner, 'SearchForm', $fields, $actions);

      return $form;

I'm trying to extend the search form to include data beyond the default specified in the FulltextSearchable file but am not sure I understand the annotation.

Enable the default configuration of MySQL full-text searching on the given data classes.
It can be used to limit the searched classes, but not to add your own classes.
For this purpose, please use {@link Object::add_extension()} directly:

Caution: This is a wrapper method that should only be used in _config.php,
and only be called once in your code.

@param Array $searchableClasses The extension will be applied to all DataObject subclasses
listed here. Default: {@link SiteTree} and {@link File}.

From this I understand that you can't just add them in as below:

public static function enable($searchableClasses = array('SiteTree', 'File', 'GalleryPage_Images')) {
      $defaultColumns = array(
         'SiteTree' => '"Title","MenuTitle","Content","MetaDescription"',
         'File' => '"Filename","Title","Content"',
         'GalleryPage_Images' => '"Caption"'

Do I need to create a custom version of the file FulltextSearchable and if wo where would this need to be stored? Or do I create a new function within the FulltextSearchable file?

I've spent some hours looking at this and am don't think I am getting any closer.

As mentioned in another post if I search for nothing all images are returned. However, as soon as you enter a search term you get nothing back.

In my config file I now have:

FulltextSearchable::enable('File'); <---- Have excluded SiteTree as I am only really interested in returning image.


I've then created a new DataObject called GalleryImage and added some data which doesn't appear to be picked up at all, even with a blank search.

Any help on this would be much appreciated. Am I heading in the right direction?

Extending FulltextSearchable is a bit of a nightmare. I'm picking all search functionality will be stripped out of core pretty soon. You could do something like
