it seems something with __prsobiproplus_tree table. Are the search from the pluding goes through that table?
On another testsite the search seems to work ok. But when I make this table empty. No searches either.
ok problem found Cronjob Mode had to be set to NO. For the smal test site the search comes back and the table filled again. But for the big website it takes more then 15 minuten and it is still searching???... how to solve this?
