FULLTEXT Operaters
Posted by: M Karim

I have installed MySQL 4.1 and created two tables, type (MyISAM Storage Engine)

TABLE1 has 200000 records
----------------------------------------
1st column:
----------------
Column name "item"
Datatype "INTEGER" "AUTOINCREMENT"
index name "PRIMARY"
index kind "PRIMARY"
index type "BTREE"

2nd column:
----------------
Column name "text"
Datatype "TEXT"
index name "text"
index kind "FULLTEXT"
index type "DEFAULT"

TABLE2 has 1000 records
------------------------------------
1st column:
----------------
Column name "item"
Datatype "INTEGER"
index name "item"
index kind "INDEX"
index type "BTREE"


I used INNER JOIN in MySQL Query as follows:

SELECT * FROM TABLE1 INNER JOIN TABLE2 ON TABLE1.item = TABLE2.item WHERE MATCH(TABLE1.text) AGAINST("keyword") LIMIT 0, 10;

ex:
SELECT * FROM TABLE1 INNER JOIN TABLE2 ON TABLE1.item = TABLE2.item WHERE MATCH(TABLE1.text) AGAINST("automobiler") LIMIT 0, 10
10 rows in set (0.00 sec)

But when I use operaters such as (*, +, - ... etc), it gives an empty set.

ex:
SELECT * FROM TABLE1 INNER JOIN TABLE2 ON TABLE1.item = TABLE2.item WHERE MATCH(TABLE1.text) AGAINST("automobil*") LIMIT 0, 10
Empty set (0.00 sec)

Also, it gives an empty set when using IN BOOLEAN MODE.

Then I installed MySQL 5.0, but unfortunately I didn't either work with operaters!!!

Is the FULLTEXT Syntax wrong??


Thanks in advance,

Best Regards,
