Search plugin (I18N)

[mvlcek]

I've tested to set a page with the tag news to private, it's still be found by the search for news tag.

Setting the visibility of a page to private and saving it will delete the search index. It will be recreated without this page whenever you do the next search. Thus this private page will not be found.
There might be steps like undo saves or similar where the search index is not recreated and thus the now private page is not removed from the index.

I.e.: it works for me and it should work for you, too. You can also try manually removeing /data/other/i18n_*_index.txt
