About the Search Process
Searches are conducted in two passes, each indicated by Search Status displayed in the Search pane (and the Task window).
Searching Databases
The existing databases are searched first. While this is the fastest search pass, this search pass can only be as accurate as the database (in other words, if the database is not completely up to date you might not find the files you want).
File System Search Pass
This is the second pass of a search. This search is not as fast as the Database pass, but it is more thorough because it is not relying on the database, which may or may not be current.
