Extended Synonym dictionary =========================== This is a simple synonym dictionary. It replaces words with groups of their synonyms, and so makes it possible to search for a word using any of its synonyms. * Configuration It accepts the following options: - KEEPORIG controls whether the original word is included, or only its synonyms. Default is 'true'. - RULES is the base name of the file containing the list of synonyms. This file must be in $(prefix)/share/tsearch_data/, and its name must end in ".rules" (which is not included in the RULES parameter). The rules file has the following format: - Each line represents a group of synonyms for a single word, which is given first on the line. Synonyms are separated by whitespace: word syn1 syn2 syn3 - Sharp ('#') sign is a comment delimiter. It may appear at any position inside the line. The rest of the line will be skipped. Look at xsyn_sample.rules, which is installed in $(prefix)/share/tsearch_data/, for an example. * Usage 1. Compile and install 2. Load dictionary psql mydb < dict_xsyn.sql 3. Test it mydb=# SELECT ts_lexize('xsyn','word'); ts_lexize ---------------- {word,syn1,syn2,syn3) 4. Change the dictionary options as you wish mydb# ALTER TEXT SEARCH DICTIONARY xsyn (KEEPORIG=false); ALTER TEXT SEARCH DICTIONARY That's all.
