# SearchContext
|
||||
|
||||
## Introduction
|
||||
[api:SearchContext] manages searching of properties on one or more [api:DataObject] types, based on a given set of
|
||||
input parameters. [api:SearchContext] is intentionally decoupled from any controller-logic, it just receives a set of
|
||||
search parameters and an object class it acts on.

Manages searching of properties on one or more `[api:DataObject]` types, based on a given set of input parameters.
|

`[api:SearchContext]` is intentionally decoupled from any controller-logic,
|
||||
it just receives a set of search parameters and an object class it acts on.
|

The default output of a [api:SearchContext] is either a [api:SQLQuery] object for further refinement, or a

[api:DataObject] instance.

The default output of a `[api:SearchContext]` is either a `[api:SQLSelect]` object for further refinement, or a

`[api:DataObject]` instance.
|
||||
|
||||
In case you need multiple contexts, consider namespacing your request parameters by using `FieldList->namespace()` on
|
||||
the $fields constructor parameter.
|
||||
|
||||
`[api:SearchContext]` is mainly used by `[ModelAdmin](/reference/modeladmin)`, our generic data administration interface. Another
|
||||
implementation can be found in generic frontend search forms through the [genericviews](http://silverstripe.org/generic-views-module) module.

Defining search-able fields on your DataObject.

||||
## Customizing fields and filters
|
||||
|
||||
In this example we're defining three attributes on our MyDataObject subclass: `PublicProperty`, `HiddenProperty`
|
||||
and `MyDate`. The attribute `HiddenProperty` should not be searchable, and `MyDate` should only search for dates
|
||||
*after* the search entry (with a `GreaterThanFilter`). Similiar to the built-in `DataObject->getDefaultSearchContext()`
|
||||
method, we're building our own `getCustomSearchContext()` variant.

summary: Fulltext search allows sophisticated searching on text content.

|

# FulltextSearchable
|
||||
|
||||
Fulltext search allows advanced search criteria for searching words within a text based data column. While basic
|
||||
Fulltext search can be achieved using the built-in [api:MySQLDatabase] class a more powerful wrapper for Fulltext
|
||||
search is provided through a module.
|
||||
|
||||
<div class="notice" markdown="1">
|
||||
See the [FulltextSearch Module](https://github.com/silverstripe-labs/silverstripe-fulltextsearch/). This module provides
|
||||
a high level wrapper for running advanced search services such as Solr, Lucene or Sphinx in the backend rather than
|
||||
`MySQL` search.
|
||||
</div>
|
||||
|
||||
## Adding Fulltext Support to MySQLDatabase
|
||||
|
||||
The [api:MySQLDatabase] class 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
|
||||
<?php
|
||||
|
||||
class MyDataObject extends DataObject {
|
||||
|
||||
private static $create_table_options = array(
|
||||
'MySQLDatabase' => 'ENGINE=MyISAM'
|
||||
);
|
||||
}
|
||||
|
||||
The [api:FulltextSearchable] extension will add the correct `Fulltext` indexes to the data model.
|
||||
|
||||
<div class="alert" markdown="1">
|
||||
The [api:SearchForm] and [api:FulltextSearchable] API's are currently hard coded to be specific to `Page` and `File`
|
||||
records and cannot easily be adapted to include custom `DataObject` instances. To include your custom objects in the
|
||||
default site search, have a look at those extensions and modify as required.

Fulltext search for page content (and other attributes like "Title" or "MetaTags") can be easily added to SilverStripe.

|

|

## 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](../customising_the_cms/modeladmin) class.
|
||||
|
||||
[SearchContext](/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 [Full module](http://silverstripe.org/sphinx-module).
