Filtering the Document Library allows you to easily search for a document inside your current case without having to scroll through the documents. Below is an example of an unfiltered Library.

Clicking into the Library Filter will display possible criteria you can use to locate documents in the case.

You can also filter by keywords by simply typing the keywords into the Library Filter and selecting the term in quotes. The below example is filtering the Library for any documents that have "IB" in their document names.

You can also filter your Library by tags to locate only documents that contain pages using specific tags.
