I'm writing a program that searches through the entire file system by file name and file contents (plain text). Is there any algorithm or open source project that could make the search very fast? I'm doing this on Windows with FAT/NTFS file systems and I don't want indexing.
Downloaded a NTFS searcher (named NTFS-Search) on SourceForce and it does the job very well! It first reads the 'FAT'once and after that it is incredibly fast. Only the interface is in German.
You can download the source with SVN:
svn co https://ntfs-search.svn.sourceforge.net/svnroot/ntfs-search
