Interfacing with the Windows Search database can be useful for various purposes, if only because it's nice to access this from Tcl. The Windows Search database is accessible using COM. Below a small example for executing a query.
package require tcom set ProgID ADODB.Connection set application [::tcom::ref createobject $ProgID] $application Open "Provider=Search.CollatorDSO;Extended Properties='Application=Windows';" set sql "SELECT Top 5 System.ItemPathDisplay FROM SYSTEMINDEX" set rst [$application Execute $sql] puts [split [$rst GetString] \r]
