Double Quotes and Full-Text Search -- Memory Exhaustion
Posted by: techupin techu

Hello,

I have a table with approximately 4 million rows. The DB Engine is InnoDB.

One of the columns is a Full-Text Index.

when I do a match(X) against ('Y')... I get the results.

when I do a match(X) against ('"Y"')... the memory gets exhausted and I get an error

``ERROR 2013 (HY000): Lost connection to MySQL server during query''

the reason for using double quotes in my against phrase is that I actually have a do a match against two consecutive words, .e.g., against('"food chain"').

I tried fiddling with the max_allowed_packet with different values in the increasing order, but no luck.

Any help greatly appreciated.

Regards,

tu.
