iMango is a supplement of Spotlight. It finds files, folders or contents in any file and diplays the results in a tree view, so that you can browse through the folder structure of the results much quicker and more intuitively than in Spotlight. Drag files onto the window (e.g. one word file from your Desktop) to quickly get an overview which subfolders of your desktop contain word files. If you can find some similar files, try selecting 2 or more of them at once and dragging them onto iMango together. iMango will search the files that contain the largest common substring - e.g. for "Annual marketing report 2013.docx" and "Annual business report 2013.xlsx" it will search all files containing "report 2013." automatically.
