For the FileSystem, the filter parameter is what you are used to in cmd.exe: *.txt, etc. The best documentation for that I can find is available from here, as the "SearchPattern": http://msdn2.microsoft.com/en-us/library/ms143316.aspx, although it ultimately relies on the support provided by the lowest-level API in Windows: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/findfirstfileex.asp
In a SQL provider, for example, it would probably be additions (in SQL):
SQL:\Database\CustomersTable > dir Customer[1-9] -filter "((City like "%Redmond%") AND (Country = "USA"))"
Allowing the provider to do the filtering is usually faster, sometimes less powerful, and inconsistent by design:
[C:\winnt\system32]
MSH:14 > measure-command { dir *.dll }
Days : 0
Hours : 0
Minutes : 0
Seconds : 2
Milliseconds : 267

Conversation: [msh] What is the '-Filter' param for on get-property, get-childit
Subject: [msh] What is the '-Filter' param for on get-property, get-childit
Both the get-property and get-childitem cmdlets support a property -Filter.
What is the Filter for?
The help in both cases says "Specifies filter elements as required and
supported by providers." which is fair enough in the sense that it's
different per provider, but still doesn't reveal much. Where would I look
to find more information about this parameter?
