htsearch - create document index and word database for the ht://Dig search engine
SYNOPSIS
htsearch [options] [query_string]
DESCRIPTION
Htsearch is used to search in de databases created by htdig for content. is the actual search engine of the htdig search system. It is a
CGI program that is expected to be invoked by an HTML form. It will accept both the GET and POST methods of passing data to the CGI pro-
gram.
OPTIONS
query_string
A CGI-style query string can be given as a single argument, and is only used if the REQUEST_METHOD environment variable is not set.
If no query_string is given, and REQUEST_METHOD is not set, htsearch will prompt for the query.
-c configfile
Use the specified configfile instead of the default (for security reasons this option is only available when htsearch is used on the
commandline).
-v -d Run in verbose mode. This increases the verbosity of the program. Using more than 2 is probably only useful for debugging pur-
poses. The default verbose mode gives a progress on what it is doing and where it is.
FILES
/etc/htdig/htdig.conf
The default configuration file.
/srv/www/htdig/common/header.html
The default search results header file
/srv/www/htdig/common/footer.html
The default search results footer file
/srv/www/htdig/common/wrapper.html
The default search results wrapper file, that contains the header and footer together in one file
/srv/www/htdig/common/nomatch.html
The default 'no matches found' HTML file
/srv/www/htdig/common/syntax.html
The default file that explains boolean expression syntax errors

htdig - retrieve HTML documents for ht://Dig search engine
SYNOPSIS
htdig [options]
DESCRIPTION
Htdig retrieves HTML documents using the HTTP protocol and gathers information from these documents which can later be used to search these
documents. This program can be referred to as the search robot.
OPTIONS
- Get the list of URLs to start indexing from standard input. This will override the default parameter start_url specified in the con-
fig file and the file supplied to the -m option.
-a Use alternate work files. Tells htdig to append .work to database files, causing a second copy of the database to be built. This
allows the original files to be used by htsearch during the indexing run.
-c configfile
Use the specified configfile instead of the default.
-h maxhops
Restrict the dig to documents that are at most maxhops links away from the starting document. This only works if option -i is also
given.
-i Initial. Do not use any old databases. Old databases will be erased before runing the program.
-m filename
Minimal run. Only index the URLs given in the file filename, ignoring all others. URLs in the file should be formatted one URL per
line. -s Print statistics about the dig after completion.
-t Create an ASCII version of the document database. This database is easy to parse with other programs so that information can be
extracted from it for purposes other than searching. One could gather some interesting statistics from this database.
Fieldname Value
u URL
t Title
a State
(0 normal, 1 not found, 2 not indexed, 3 obsolete)
m Time of last modification reported by the server
s Document Size in bytes
H Excerpt of the document
h Meta Description
l Time of last rerievial
L Count of links in the document or of outgoing links
b Number of links to the document, also called
incoming links or backlinks
c Hop count of this document
g Signature of this document
(used to detect duplicates)
e E-Mail address to use for a notification from htnotify
n Date on which such notification is sent
S Subject of the notfication message
d The text of Incoming links pointing to this document
(e.g. <a href="docURL">description</a>)
A Anchors in the document (i.e. <A NAME=...)
-u username:password
Tells htdig to send the supplied username and password with each HTTP request. The credentials will be encoded using the 'Basic'
authentication method. There HAS to be a colon (:) between the username and password.
-v Verbose mode. This increases the verbosity of the program. Using more than 2 is probably only useful for debugging purposes. The
default verbose mode (using only one -v) gives a nice progress report while digging. Please consult the section below on the exact
format of the progress report.
FORMAT OF THE PROGRESS REPORT GIVEN IN VERBOSE MODE
A line is shown for each URL, with 3 numbers before the URL and some symbols after the URL. The first number is the number of docu-
ments parsed so far, the second is the DocID for this document, and the third is the hop count of the document (number of hops from
one of the start_url documents). Signification of the sybols printed after the url:
"*" is printed for a link already visited
"+" is printed for a new link just queued
"-" is output for a link rejected for any of a number of reasons. To find out what those reasons are, you need to run htdig with at
least 3 -v options, i.e. -vvv.
If there are no "*", "+" or "-" symbols after the URL, it doesn't mean the document was not parsed or was empty, but only that no links to
other documents were found within it. With more verbose output, these symbols will get interspersed in several lines of debugging output.
FILES
/etc/htdig/htdig.conf
The default configuration file. /var/lib/htdig/db/db.docdb Stores data about each document (title, url, etc.).
/var/lib/htdig/db/db.words.db, /var/lib/htdig/db/db.words.db_weakcmpr Record which documents each word occurs in.
/var/lib/htdig/db/db.excerpts Stores start of each document to show context of matches.
