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.
