använd en myisam fulltexttabell för att indexera tillbaka till dina innodb-tabeller till exempel:
Bygg ditt system med hjälp av 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;
Nu fulltextsöktabellen som vi kommer att använda bara för att indexera tillbaka till våra innodb-tabeller. Du kan underhålla rader i den här tabellen antingen genom att använda en trigger eller nattliga batchuppdateringar 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;
Slutligen den lagrade sökproceduren som du anropar från din php/applikation:
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');
Hoppas detta hjälper :)
