Is it safe to truncate this table (index_rel)? According to this: http://www.dirkgomez.de/en/typo3-indexed-search-and-tt-news-index-rel-growth it should be? Table is used for indexed search? I'm doing upgrade so converting this table from myisam to innodb takes a long time (8 hours) so if it's safe to truncate it i'll do that. Thx. Regards.
