Missing implementation of filterTermAccessor in MatTableDataSource.

Bug, feature request, or proposal:

Missing implementation of filterTermAccessor in MatTableDataSource.

What is the expected behavior?

There should be the implementation of filterTermAccessor in MatTableDataSource so that it can be overridden.

What is the current behavior?

There is no implementation of filterTermAccessor in MatTableDataSource. Only comments are added for the uses of the same. I have searched the entire git repo but did not found any implementation.

What are the steps to reproduce?

Providing a StackBlitz reproduction is the best way to share your issue.

StackBlitz starter: https://goo.gl/wwnhMV

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Is there anything else we should know?

Just encountered this. The docs clearly state

MatTableDataSource extends DataSource
Data source that accepts a client-side data array and includes native support of filtering, sorting (using MatSort), and pagination (using MatPaginator).

Allows for sort customization by overriding sortingDataAccessor, which defines how data properties are accessed. Also allows for filter customization by overriding filterTermAccessor, which defines how row data is converted to a string for filter matching.

However only sortingDataAccessor is present.

Hi,

This issue is still present. I spent some time trying to understand where is this method. Would be nice to fix it, as it's from 2018.
