=== Searching for content ===
To seach for content in pages and return page titles that much, we have to revert the process:
==== get old_id of matching page ====
select old_id from text where old_text LIKE "%finn%" limit 5;
we get a list like
+--------+
| old_id |
+--------+
| 19561 |
| 12621 |
| 12622 |
| 12682 |
| 12683 |
+--------+
Now we would have to check for all of them
==== get rev_id's from old_id's ====
select rev_id from revision where rev_text_id IN (19561,12621,12622,12682,12683);
+--------+
| rev_id |
+--------+
| 12621 |
| 12622 |
| 12682 |
| 12683 |
| 19561 |
+--------+

Ok, enough of trying to find the right queries after the upgrade to 1.5 mediawiki.
Lets just log the sql queries from the server.
A page being requested
get page_id
SELECT page_id FROM `page` WHERE page_namespace = '0' AND page_title = 'Ogg' LIMIT 1;
get page_latest
SELECT page_id,page_namespace,page_title,page_restrictions,page_counter,page_is_redirect,page_is_new,page_random,page_touched,page_latest,page_len FROM `page` WHERE page_id = '17369' LIMIT 1;
after having page_latest (32808) ,which is = rev_id in revision we can:
get revision_text_id
SELECT rev_text_id from revision where rev_id=32808;
after having rev_text_id (32770), which is = old_id, we can finally:
get the actual content
SELECT old_text,old_flags FROM `text` WHERE old_id = '32770';
brion: mutante: old_id=rev_text_id brion: rev_id=page_latest
