Answer 1

$WepApp = "http://myCo.root.site/"
$site = Get-SPSite $WepApp
$array = @("Title of the First Site", "Title of the Second Site")
$filteredWebs = $site | Get-SPWeb | ? {$array -contains $_.Title}

Or you can have URLs in the array and filter by by $_.Url.

You're really, really close...

$WebApp = Get-SPWebApplication "<your webapp address here>"
$site = Get-SPSite $WebApp
$site.AllWebs | Where-Object { $_.Title -contains $yourstringfilterwhateveritis }

This is a very common issue which comes up when we upgrade SharePoint or add Package . One need to add the SPDataAccess role to the respective users so that user can manipulate the content database. Please find step of procedure to resolve the issue.

• In Object Explorer, expand the Security node, and then double-click on the search service account (eg, spSearch). The Login Properties dialog appears.
• In the Select a page navigation panel, select User Mapping.
• In the Users mapped to this login panel, select the farm configuration database (eg, farm_Config).
• Enable the SPDataAccess role
• Click OK.
