An apostrophe / single quote (') should be part of a word in a FULLTEXT index.
Admittedly I can't find this on the MariaDB website, but I'm assuming it should still behave like MySQL (version 5.5).
But when using "IN BOOLEAN MODE", and prefixing the word with a "+" (so it's mandatory in all rows returned), the record is not returned.
For example:
CREATE TABLE customer (
name TINYTEXT NOT NULL,
FULLTEXT (name)
) ENGINE = InnoDB;
INSERT INTO customer VALUES ('O''Brien');
INSERT INTO customer VALUES ('O Brien');
INSERT INTO customer VALUES ('X''Brien');
INSERT INTO customer VALUES ('Extra Amy');
INSERT INTO customer VALUES ('Extra Brian');
INSERT INTO customer VALUES ('Extra Cat');
INSERT INTO customer VALUES ('Extra Debbie');
I get these results:
SELECT * FROM customer WHERE MATCH (name) AGAINST ("O'Brien" IN BOOLEAN MODE);
"O'Brien"
"O Brien"
"X'Brien"
3 rows in set (0.000 sec)
SELECT * FROM customer WHERE MATCH (name) AGAINST ("+O'Brien" IN BOOLEAN MODE);
Empty set (0.000 sec)
SELECT * FROM customer WHERE MATCH (name) AGAINST ("+Brien" IN BOOLEAN MODE);
"O'Brien"
"O Brien"
"X'Brien"
3 rows in set (0.000 sec)
SELECT * FROM customer WHERE MATCH (name) AGAINST (+"O'Brien" IN BOOLEAN MODE);
"O'Brien"
"O Brien"
"X'Brien"
3 rows in set (0.000 sec)
Am I missing something, like needing to quote the apostrophe?
Or is this an intentional difference between InnoDB and MyISAM?
Thanks to @rick-james, I've updated this question to include 3 "extra" records to avoid the 50% threshold limit, and I've included an example where the +
is before the quoted word.
