Narrative Version

Once the user has already installed the software and added tags to their files, the user opens up the search application. The user is able to search with three different criteria, required, one word required, and words to be excluded. In other words, the capability to search using AND, OR, NOT queries. The user enters in any combinations or "AND, OR, NOT" key words and selects to search. The program searched for all files matching the query created by the user and then displays all of the files to the user, with direct links to the user so the user can open or edit the file directly from the application.
