htdig(1) General Commands Manual htdig(1)NAME
htfuzzy - fuzzy command-line search utility for the ht://Dig search engine
SYNOPSIS
htfuzzy [-c configfile] [-v] algorithm [options]
DESCRIPTION
Description to follow here
OPTIONS -c configfile
Use the specified configfile instead of the default.
-v Verbose mode Use this to get more verbose output while running htfuzzy. More than one v can be specified (ie. -vv , -vvv
etc ). Specifying more than two v's is probably only useful for debugging purposes.
Supported Algorithms
Different algorithms are supported for searching:
soundex Creates a slightly modified soundex key database. Differences with the standard soundex algorithm are: Keys are 6 digits
and the first letter is also encoded. metaphone Creates a metaphone key database. This algorithm is more specific to English,
but will get fewer "weird" matches than the soundex algorithm.
accents (No description of the algorithm at the moment)
endings Creates two databases which can be used to match common word endings. The creation of these databases requires a list
of affix rules and a dictionary which uses those affix rules. The format of the affix rules and dictionary files are the ones
used by the ispell program. Included with the distribution are the affix rules for English and a fairly small English dictionary.
Other languages can be supported by getting the appropriate affix rules and dictionaries. These are available for many languages;
check the ispell distribution for more details.
synonyms Creates a database of synonyms for words. It reads a text database of synonyms and creates a database that htsearch can
then use. Each line of the text database consists of words where the first word will have the other words on that line as synonyms.
Notes on searching
Please consult specialised literature to find out how the different algorithms work or simply try another
search strategy you do not get the intended search results.

htload - reads in an ASCII-text version of the document database
SYNOPSIS
htload [options]
DESCRIPTION
Htload reads in an ASCII-text version of the document database in the same form as the -t option of htdig and htdump. Note that this
will overwrite data in your databases, so this should be used with great care.
OPTIONS -a Use alternate work files. Tells htload to append .work to database files, allowing it to operate on a second set of databases.
-c configfile
Use the specified configfile instead of the default.
-i Initial. Do not use any old databases. This is accomplished by first erasing the databases.
-v Verbose mode. This doesn't have much effect.
File Formats
Document Database
Each line in the file starts with the document id followed by a list of fieldname : value separated by tabs. The fields always
appear in the order listed below:
u URL
t Title
a State (0 = normal, 1 = not found, 2 = not indexed, 3 = obsolete)
m Last modification time as reported by the server
s Size in bytes
H Excerpt
h Meta description
l Time of last retrieval
L Count of the links in the document (outgoing links)
b Count of the links to the document (incoming links or backlinks)
c HopCount of this document
g Signature of the document used for duplicate-detection
e E-mail address to use for a notification message from htnotify
n Date to send out a notification e-mail message
S Subject for a notification e-mail message
d The text of links pointing to this document. (e.g. <a href="docURL">description</a>)
A Anchors in the document (i.e. <A NAME=...)
Word Database
While htdump and htload don't deal with the word database directly, it's worth mentioning it here because you need to deal with it
when copying the ASCII databases from one system to another. The initial word database produced by htdig is already in ASCII format,
and a binary version of it is produced by htmerge, for use by htsearch. So, when you copy over the ASCII version of the document
database produced by htdump, you need to copy over the wordlist as well, then run htload to make the binary document database on the
target system, followed by running htmerge to make the word index.
Each line in the word list file starts with the word
followed by a list of fieldname : value separated by tabs. The fields always appear in the order listed below, with the last two
being optional:
i Document ID
l Location of word in document (1 to 1000)
w Weight of word based on scoring factors
c Count of word's appearances in document, if more than 1
a Anchor number if word occurred after a named anchor
