title: SearchFilter Modifiers
summary: Use suffixes on your ORM queries.
# SearchFilter Modifiers
The `filter` and `exclude` operations specify exact matches by default. However, there are a number of suffixes that
you can put on field names to change this behavior. These are represented as `SearchFilter` subclasses and include.
* [api:StartsWithFilter]
* [api:EndsWithFilter]
* [api:PartialMatchFilter]
* [api:GreaterThanFilter]
* [api:GreaterThanOrEqualFilter]
* [api:LessThanFilter]
* [api:LessThanOrEqualFilter]
An example of a `SearchFilter` in use:
:::php
// fetch any player that starts with a S
$players = Player::get()->filter(array(
'FirstName:StartsWith' => 'S'
'PlayerNumber:GreaterThan' => '10'
));
// to fetch any player that's name contains the letter 'z'
$players = Player::get()->filterAny(array(
'FirstName:PartialMatch' => 'z'
'LastName:PartialMatch' => 'z'
));
Developers can define their own [api:SearchFilter] if needing to extend the ORM filter and exclude behaviors.
These suffixes can also take modifiers themselves. The modifiers currently supported are `":not"`, `":nocase"` and
`":case"`. These negate the filter, make it case-insensitive and make it case-sensitive, respectively. The default
comparison uses the database's default. For MySQL and MSSQL, this is case-insensitive. For PostgreSQL, this is
case-sensitive.
The following is a query which will return everyone whose first name starts with "S", either lowercase or uppercase:
:::php
$players = Player::get()->filter(array(
'FirstName:StartsWith:nocase' => 'S'
));
// use :not to perform a converse operation to filter anything but a 'W'
$players = Player::get()->filter(array(
'FirstName:StartsWith:not' => 'W'
));
