Note: If you haven’t activated Cortana, you can still use these natural language search terms; however, in my experience they aren’t quite as powerful when using plain vanilla Windows 10 search.
You can’t use Cortana’s natural language to find everything—in my tests, music files were out, for example. But when you want to do a quick search for that photo you snapped yesterday or the video of your kids from last week, Cortana can help.
When you’re looking for files using Cortana, the most important terms to remember are “show me” or “find.” Almost every search will begin with that phrase, such as, “Show me pictures from last week” or “Show me documents from February.” In my experience, these general searches work fairly well, but sometimes items you expect to be there are missing from the results.
The great advantage of natural language search is you can get far more specific than just asking for images by month. If you use OneDrive’s camera roll feature, for example, you can ask Cortana something like, “Show me pictures from my Camera Roll from March 2nd.”
Finding a document using keywords and general locations works as well, such as, “Show me documents from this device with ‘cyber’ in the title” or “Find documents about chess in OneDrive.” You can also use terms like “on my PC” in lieu of “this device.”
Searching OneDrive has one last handy feature thanks to the addition of optical character recognition for photos that Microsoft added to its cloud storage service just over a year ago. Say you snapped an image of a recipe for chicken wings, you can say, “Show me buffalo wings pictures in OneDrive.” For this search you must specify location since Cortana might assume you’re asking to search the web, not your files.
Natural language search in Windows 10 is a powerful tool. It’s not perfect, but more often than not it can get the job done.
