PDFlib TET PDF IFilter 4.0 Manual

SQL queries for metadata properties. SQL queries can search for predefined as well as
custom properties. Some examples are provided below; they assume that indexing of
all predefined properties has been enabled in the XML configuration file, and that the
predefined_properties.propdesc property description has been registered. We use ADO
(ActiveX Data Objects) and PowerShell scripts to submit SQL-based queries. However, you
can use the SQL statements in any other ADO or ADO.NET environment as well. A description
of the SQL syntax extensions for Windows search is available at
msdn.microsoft.com/en-us/library/bb231256(VS.85).aspx
Property searches can be applied in two directions:
> Query a specific property value: which documents have Doyle as author?
> Query the value of a specific property in one or more files: who is the author of this
document?
PowerShell for submitting SQL queries. Windows PowerShell is included in Windows 7
and Windows Server 2008, and can be installed on Windows XP SP2, Windows Server
2003, and Windows Vista. The installation files can be downloaded from the following
location:

Sample PowerShell query scripts are installed with TET PDF IFilter. The following Power-
Shell script lists all bookmarks for all documents:
$objConnection = New-Object -comobject ADODB.Connection
$objRecordset = New-Object -comobject ADODB.Recordset
$objConnection.Open("Provider=Search.CollatorDSO;Extended
Properties='Application=Windows';")
$objRecordSet.Open(
"SELECT System.ItemPathDisplay, `"PDFlib.TETPDFIFilter.bookmark`" FROM SYSTEMINDEX ",
$objConnection)
While ($objRecordset.EOF -ne $True) {
$private:item = $objRecordset.Fields.Item("System.ItemPathDisplay")
Write-Output $item.Value
$item = $objRecordset.Fields.Item("PDFlib.TETPDFIFilter.bookmark")
Write-Output $item.Value
$objRecordset.MoveNext()
}
The following PowerShell script lists all documents where at least one bookmark contains
the text alpha:
$objConnection = New-Object -comobject ADODB.Connection
$objRecordset = New-Object -comobject ADODB.Recordset
$objConnection.Open("Provider=Search.CollatorDSO;Extended
Properties='Application=Windows';")
$objRecordSet.Open("SELECT System.ItemPathDisplay FROM SYSTEMINDEX WHERE " +
"`"PDFlib.TETPDFIFilter.bookmark`" = SOME ARRAY ['alpha']", $objConnection)
While ($objRecordset.EOF -ne $True) {
$private:item = $objRecordset.Fields.Item("System.ItemPathDisplay")
Write-Output $item.Value
