use una tabla de texto completo de myisam para volver a indexar sus tablas de innodb, por ejemplo:
Construya su sistema usando innodb:
create table users (...) engine=innodb;
create table forums (...) engine=innodb;
create table threads
(
forum_id smallint unsigned not null,
thread_id int unsigned not null default 0,
user_id int unsigned not null,
subject varchar(255) not null, -- gonna want to search this... !!
created_date datetime not null,
next_reply_id int unsigned not null default 0,
view_count int unsigned not null default 0,
primary key (forum_id, thread_id) -- composite clustered PK index
)
engine=innodb;
Ahora la tabla de búsqueda de texto completo que usaremos solo para volver a indexar en nuestras tablas innodb. Puede mantener filas en esta tabla mediante el uso de un disparador o actualizaciones por lotes nocturnas, etc.
create table threads_ft
(
forum_id smallint unsigned not null,
thread_id int unsigned not null default 0,
subject varchar(255) not null,
fulltext (subject), -- fulltext index on subject
primary key (forum_id, thread_id) -- composite non-clustered index
)
engine=myisam;
Finalmente, el procedimiento almacenado de búsqueda al que llama desde su php/aplicación:
drop procedure if exists ft_search_threads;
delimiter #
create procedure ft_search_threads
(
in p_search varchar(255)
)
begin
select
t.*,
f.title as forum_title,
u.username,
match(tft.subject) against (p_search in boolean mode) as rank
from
threads_ft tft
inner join threads t on tft.forum_id = t.forum_id and tft.thread_id = t.thread_id
inner join forums f on t.forum_id = f.forum_id
inner join users u on t.user_id = u.user_id
where
match(tft.subject) against (p_search in boolean mode)
order by
rank desc
limit 100;
end;
call ft_search_threads('+innodb +clustered +index');
Espero que esto ayude :)
