GLIMPSE 3.5: searching entire file systems
(http://glimpse.cs.arizona.edu/)
Glimpse is a very powerful indexing and query system that allows you to
search through all your files very quickly. It can be used by
individuals for their personal file systems as well as by organizations
for large data collections. Glimpse is also the basis of GlimpseHTTP,
which provides search for web sites, and it is the default search engine
in Harvest (see below).
Glimpseindex, which you run by saying "glimpseindex DIR" builds an
index of all text files in the tree rooted at DIR.
(e.g., glimpseindex ~ indexes all your files.) With it, glimpse can
search through all files much the same way as agrep (or any other
grep), except that you don't have to specify file names and the search
is fast. For example,
glimpse -1 unbelievable
will find all occurrences (in all your files!) of "unbelievable"
allowing one spelling error;
glimpse -F mail arizona
will find all occurrences of "arizona" in all files with "mail" somewhere
in their name;
glimpse 'Arizona desert;windsurfing'
will find all lines that contain both "Arizona desert" and "windsurfing".
Glimpse supports three types of indexes: a tiny one (2-3% of the
size of all files), a small one (7-9%), and a medium one (20-30%).
The larger the index the faster the search.
Glimpse supports most of agrep's options (agrep is our powerful version
of grep, and it is part of glimpse) including approximate matching
(e.g., finding misspelled words), Boolean queries, and even some
limited forms of regular expressions.
The WWW home page for glimpse is in

It includes links to the source, binaries for most UNIX systems,
documentations, articles, and more.
GlimpseHTTP home page is in

Harvest's WWW home page is

(Harvest is an integrated set of tools to gather, extract,
organize, search, cache, and replicate relevant information
across the Internet.)
Mail glimpse-request@cs.arizona.edu to be added to the glimpse mailing list.
Mail glimpse@cs.arizona.edu to report bugs, ask questions, discuss
tricks for using glimpse, etc. (This is a moderated mailing list.)

* Glimpse version 4.0B1 (beta) has been released on Nov. 22, 1996.
See the announcement (and you can download it below). Glimpse now
supports NOT. (As opposed to NOT supporting it before....) If you
use 4.0, you will have to reindex.

Introduction
Glimpse is a very powerful indexing and query system that allows you
to search through all your files very quickly. It can be used by
individuals for their personal file systems as well as by
organizations for large data collections. Glimpse is the default
search engine in Harvest. Glimpse is now at version 4.0B1.
The Glimpse package contains several programs, the most important of
which are glimpse, glimpseindex, agrep, and glimpseserver. To index
all files in the a directory tree rooted at DIR, you simply say
glimpseindex DIR
(E.g., glimpseindex ~ indexes all your files.) Afterwards, glimpse can
search through all these files much the same way as agrep (or any
other grep), except that you don't have to specify file names and the
search is fast. For example,
glimpse -1 unbelievable
will find all occurrences (in all your files!) of "unbelievable"
allowing one spelling error;
glimpse -F mail arizona
will find all occurrences of "arizona" in all files with "mail"
somewhere in their name;
glimpse 'Arizona desert;windsurfing'
will find all lines that contain both "Arizona desert" and
"windsurfing".
glimpse -W 'Arizona;~football'
will find all lines containing "Arizona" in files that do not contain
the word "football".
Glimpse supports three types of indexes: a tiny one (2-3% of the size
of all files), a small one (7-9%), and a medium one (20-30%). The
larger the index the faster the search. For most applications, the
small index (glimpseindex -o) is the best choice. Glimpse supports
most of agrep's options (agrep is our powerful version of grep, and it
is part of glimpse) including approximate matching (e.g., finding
misspelled words), Boolean queries, and even some limited forms of
regular expressions.
