Learning Windows Search: Use Advanced Query Syntax to Find Everything: "When you perform a search using AQS, you start with a search query. This can include one or two keywords, which can include a simple phrase such as “to be or not to be” or a file name “img2467.jpg.” You can also string together queries with Boolean and optional search operators including content, data stores where a file resides, the kind of file, and the properties of a file."
