Question

I’m trying to find “the zen” string in a field containing “The Zen Circus”.
I’ve got a FULLTEXT index.

select url,name,
,   MATCH(name) AGAINST ( 'zen*' IN BOOLEAN MODE) as A
,   MATCH(name) AGAINST ( '"the zen*"' IN BOOLEAN MODE) as B
,   MATCH(name) AGAINST ('>the* zen' IN BOOLEAN MODE) as C
,   MATCH(name) AGAINST ('thezen*' IN BOOLEAN MODE) as D
,   MATCH(name) AGAINST ('cir*' IN BOOLEAN MODE) as E
,   MATCH(name) AGAINST ('circus*' IN BOOLEAN MODE) as F
from pages where url='thezencircus'

I’ve got this result:

url = thezencircus
name = The Zen Circus
A = 0   (why?)
B = 0   (why?)
C = 0   (why?)
D = 0   (ok)
E = 1   (ok)
F = 1   (ok)

I’ve also putted ft_min_word_len = 2 in the msyql config file.

Any idea?

Answer 1

See this answer MySQL full text search for words with three or less letters

[mysqld]
ft_min_word_len=3
Then you must restart the server and rebuild your FULLTEXT indexes.

Remeber to restart and rebuild indexes.

Edit
Run show variables like 'ft_%'; to confirm that the word length matches what you set it to.
