Using Get-SPSite -Filter

Question

I seem to be having some trouble using the Filter parameter on the Get-SPSite cmdlet.

Using this question for reference, I'd hoped to filter out the Site that I was getting, to later on exclude it from being moved outside the Content DB.

I'm getting an error on the line;

Get-SPSite -Filter {$_.Url -ne "http://mysites.dev.local/"} -ContentDatabase "WSS_Content_MySites" -Limit 1 

The error being:

Get-SPSite : Not a valid filter string format. The format is (property) (operator) (value).

I don't seem to be doing anything differently from the aforementioned question. Could anyone help?

Answer Edit:

From this blog, I found this little gem:

The filter parameter support is as follows:

a. SPWeb supports: Title and Template

b. SPSite and SPSiteAdministration supports: Owner, SecondaryContact, and LockState

It seems the -Filter parameter is very limited in what it can provide, and thus in this instance, was necessary to use a Where-Object

Answer 1

Check Get-SPSite documentation:

The Filter parameter is a server-side filter for certain site collection properties that are stored in the content database; without the Filter parameter, filtering on these properties is a slow process. These site collection properties are Owner, SecondaryOwner, and LockState. The Filter parameter is a script block that uses the same syntax as a Where-Object statement, but is run on the server for faster results.

I think it's stated we can't filter by anything except Owner, SecondaryOwner, LockState in Get-SPSite -filter. Matches my experiments. Let's see documentation on Get-SPWeb:

The Filter parameter is a server-side filter for certain subsite properties that are stored in the content database; without the Filter parameter, filtering on these properties is a slow process. These subsite properties are Template and Title. The Filter parameter is a script block that uses the same syntax as a Where-Object statement, but is run server-side for faster results.

I read it like this: we can't filter by anything except Template, Title in Get-SPWeb -filter.

So

Get-SPSite -Filter {$_.Url -ne "http://mysites.dev.local"}

will not work and should be replace with semantically equivalent

Get-SPSite | ? {$_.Url -ne "http://mysites.dev.local"}

Answer 2

You can use | Where, for example:

Get-SPSite | where{$_.Url.Startswith("http://intranet....")}
