ClusterView is a Windows 95 application designed to help handle text
searching tasks in a group of large files. They can be either plain text
files (like documentation files) or HTML source files (like those you
can get back from Internet with the help of the "save page" feature of
Netscape, Mosaic or the Internet Explorer). It's often difficult to
handle all these different files, ClusterView allows to view them (for
HTML files it provides a fast viewing mechanism with none of the flashy
features of the full-fledged programs), and then to search in the group
of 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. It's easy to build a
cluster for all HTML documents of the cache directory for NetScape or
Mosaic.

- 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.

- 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.

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

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
   YGREP32.DLL  Support DLL

   YGREP.TXT    Description of the YGrep Search Engine support DLL
   BITLIST.TXT  Description of the BitList Engine
   ORDER.TXT    Minimal order form


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 either in the ClusterView directory, or in a directory on your path,
and try again. Eventually, move YGREP32.DLL to the C:\WINDOWS directory.
