● stopwordTable=[.]
SELECT TO_DECIMAL(SCORE(),3,2) as score, company FROM mydata
WHERE CONTAINS(company, 'xy gmbh', FUZZY(0.7, 'textsearch=compare,
stopwordTable=MYSTOPWORDS, stopwordListId=legalform'))
ORDER BY score DESC;
To activate language-specific stopwords, you must provide the language parameter:
SELECT TO_DECIMAL(SCORE(),3,2) as score, company FROM mydata
WHERE CONTAINS(company, 'xy gmbh', FUZZY(0.7, 'textsearch=compare,
stopwordTable=MYSTOPWORDS, stopwordListId=legalform'), language('de'))
ORDER BY score DESC;
Note: In this case, all stopwords where language_code is set to 'de' or empty will be used. Any stopwords
with other language codes will be ignored.
Stopwords are removed from the search term first. In this example, the result set of the search is the same as for
the search '... WHERE CONTAINS(company, 'xy', ...'.
When calculating the score, the fuzzy scores of the non-stopword terms have the biggest influence on the
resulting score. Stopwords in the user input and in the database records are also given less weight than the non-
stopword terms, so records with matching stopwords get a higher score than records with differing or missing
stopwords.
The result of the above example is as follows:
Score Company Comment
1.00 XY GmbH
0.95 XY Missing stopword
0.95 XY Aktiengesellschaft Differing stopword
0.92 XY Gesellschaft mit beschränkter
Haftung
Many differing stopwords
0.78 XY Company Additional non-matching term, no
stopword
The value given for stopwordTable can be any valid SQL identifier as defined in the SQL reference manual. If
schema is omitted, the current schema is used. The following examples all reference the same stopword table.
SET SCHEMA schema1;
SELECT ... WHERE CONTAINS(c, 'xy', FUZZY(0.7,
'stopwordTable=schema1.mystopwords, ...'))...;
SELECT ... WHERE CONTAINS(c, 'xy', FUZZY(0.7,
'stopwordTable="SCHEMA1"."MYSTOPWORDS", ...'))...;
SELECT ... WHERE CONTAINS(c, 'xy', FUZZY(0.7,
'stopwordTable=mystopwords, ...'))...;
