Searching for Pages (and Files)
Fulltext search for page content (and other attributes like "Title" or "MetaTags") can be easily added to SilverStripe. See Tutorial: Site Search for details.
Searching for DataObjects
The [api:SearchContext] class provides a good base implementation that you can hook into your own controllers.
A working implementation of searchable DataObjects can be seen in the [ModelAdmin](/reference/modeladmin) class.
SearchContext goes into more detail about setting up a default search form for [api:DataObject]s.
Fulltext search on DataObjects
The [api:MySQLDatabase] class now defaults to creating tables using the InnoDB storage engine. As Fulltext search in MySQL
requires the MyISAM storage engine, any DataObject you wish to use with Fulltext search must be changed to use MyISAM storage
engine.
You can do so by adding this static variable to your class definition:
:::php
private static $create_table_options = array(
'MySQLDatabase' => 'ENGINE=MyISAM'
);
Searching for Documents
SilverStripe does not have a built-in method to search through file content (e.g. in PDF or DOC format).
You can either extract any textual file content into the [File](api:File)->Content property, or use a
dedicated search service like the sphinx module.
