fuzzy command-line search utility for the ht://Dig search engine


htfuzzy [-c configfile] [-v] algorithm [options]


Description to follow here


-c configfile

Use the specified configfile instead of the default.


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. 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 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.
