Dictionary for integers
=======================
The motivation for this example dictionary is to control the indexing of
integers (signed and unsigned), and, consequently, to minimize the number of
unique words which greatly affect the performance of searching.
* Configuration
The dictionary accepts two options:
- The MAXLEN parameter specifies the maximum length (number of digits)
allowed in an integer word. The default value is 6.
- The REJECTLONG parameter specifies if an overlength integer should be
truncated or ignored. If REJECTLONG=FALSE (default), the dictionary returns
the first MAXLEN digits of the integer. If REJECTLONG=TRUE, the
dictionary treats an overlength integer as a stop word, so that it will
not be indexed.
* Usage
1. Compile and install
2. Load dictionary
psql mydb < dict_int.sql
3. Test it
mydb# select ts_lexize('intdict', '12345678');
ts_lexize
-----------
{123456}
4. Change its options as you wish
mydb# ALTER TEXT SEARCH DICTIONARY intdict (MAXLEN = 4, REJECTLONG = true);
ALTER TEXT SEARCH DICTIONARY
That's all.

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.
