Windows Search command-line client
This is a simple Python script for searching Windows Search from the command line, returning results on stdout, one per line. Basically, it gives you an interface like locate or tracker-search to WDS, which is rather useful for using it from things like anything.el.
Download the script from here. I recommend that you install it in your PYTHONPATH and call it with "python -m DesktopSearch [search terms]", because argument parsing, especially with quotes, can be somewhat dodgy on Windows, especially when you are mixing CMD.exe and Cygwin bash environments. The script only takes keywords, and does not support the "Advanced Query Syntax". It also only returns paths to plain files, not indexed URLs or Outlook messages.
