A system and related techniques accept user-inputted search terms, for example to perform a search for files or other data or objects. According to embodiments, an extension of a search to different levels or points in the file system hierarchy may be automatically generated and presented to the user as a selectable search box. That box may be highlighted to the user for easy selection. When the user selects the selectable search box, the user's search for files of type or extension “.doc” or “.memo”, may be seamlessly extended to other files, folders, trees or other points or levels in the file system hierarchy. Search results may be continuously or dynamically updated as the user enters more characters or other data.
