ClusterView is a Windows 95 application designed to help handle text
searching tasks in a group of large files. The most prominent features
are:

- grouping of documents in a structure named "cluster". This allows to
consult simultaneously various files you decide to link together
according to your needs. Various operations (other than mere viewing)
can be applied to the documents of a cluster.

- most of the keyboard commands are similar to / compatible with the
ones from the Unix utilities named MORE and LESS.

- files viewing is not limited by any constraints of size. You can be
viewing anything you want (even gigabytes files if your computer has
them readable - e.g. from a network).

- capability of using ClusterView over Windows 3.1 using the Win32s
wrapping. This allows to get the 32-bit performance without upgrading
to Win95 or WinNT.

- some display processing allows to filter/modify the presentation of
data to the document window.

- approximative search based on Baeza-Yates algorithm to find a pattern
which is only partly known (also known as search with erroneous
patterns). For example, you can search for "pattern" with 1 error (at
most) and it will match "pattern", "pittern" and "Pattern" while
stepping over "lantern" (2 errors).

- search modelled on the Unix utility named GREP. It is particularly
useful for complex searching with the help of its specific search
"language" to describe the pattern you look for. For example, you can
search for "^pattern" to look for "pattern" at the beginning of a line;
or for "[pl]a[nt]tern" to look for either "pattern" or "lantern". Look
into the Help file for an extensive description of the pattern language.

Both search methods are particularly useful to tackle large amounts of
data when you are looking for important but difficult to locate data.


The Windows help file gives detailed information about using it.

File List:

   CLUSTER.EXE  The executable file
   CLUSTER.HLP  Help file
   CLUSTER.TXT  This file
   YGREP.DLL    Support DLL

   YGREP.TXT    Description of the YGrep Search Engine support DLL
   BITLIST.TXT  Description of the BitList Engine

To install ClusterView, simply put all the files in any directory
already included in your path (C:\WINDOWS is suggested). If you already
have an earlier version of ClusterView, replace its old files by the new
ones.

If Windows cannot find the DLL when the application is run, make sure it
is in a directory on your path, and try again. Eventually, move
YGREP.DLL to the C:\WINDOWS directory.
