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 , -vvv
               etc ). Specifying more than two v’s is probably only useful for
              debugging purposes.


Supported Algorithms

       Different algoritms are supported for searching:
              soundex  Creates  a slightly modified soundex key database. Dif-
              ferences 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  spe-
              cific  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 distribu-
              tion  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  distribu-  tion  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 stragegy you do not get the intended search results.
