@ -67,6 +67,51 @@ Note: There's usually a connector-specific "reindex" task for this.
Note that for most connectors, changes won't be searchable until _after_ the request that triggered the change.
The return value of a `search()` call is an object which contains a few properties:
* `Matches`: ArrayList of the current "page" of search results.
* `Suggestion`: (optional) Any suggested spelling corrections in the original query notation
* `SuggestionNice`: (optional) Any suggested spelling corrections for display (without query notation)
* `SuggestionQueryString` (optional) Link to repeat the search with suggested spelling corrections
## Controllers and Templates
In order to render search results, you need to return them from a controller.
You can also drive this through a form response through standard SilverStripe forms.
In this case we simply assume there's a GET parameter named `q` with a search term present.
class Page_Controller extends ContentController {
private static $allowed_actions = array('search');
public function search($request) {
$query = new SearchQuery();
$query->search($request->getVar('q'));
return $this->renderWith('array(
'SearchResult' => singleton('MyIndex')->search($query);
);
}
}
In your template (e.g. `Page_results.ss`) you can access the results and loop through them.
They're stored in the `$Matches` property of the search return object.
<% if SearchResult.Matches %>
<h2>Results for &quot;{$Query}&quot;</h2>
<p>Displaying Page $SearchResult.Matches.CurrentPage of $SearchResult.Matches.TotalPages</p>
<ol>
<% loop SearchResult.Matches %>
<li>
<h3><a href="$Link">$Title</a></h3>
<p><% if Abstract %>$Abstract.XML<% else %>$Content.ContextSummary<% end_if %></p>
</li>
<% end_loop %>
</ol>
<% else %>
<p>Sorry, your search query did not return any results.</p>
<% end_if %>
Please check the [pagination guide](http://docs.silverstripe.org/en/3.2/developer_guides/templates/how_tos/pagination/)
in the main SilverStripe documentation to learn how to paginate through search results.
## Searching Specific Fields
By default, the index searches through all indexed fields.
