Take: https://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=%22above—then%22%7E0&fulltext=Search&ns8=1&ns9=1&profile=advanced and: https://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=%22above—then%22%7E0&fulltext=Search&ns0=1&ns1=1&ns8=1&ns9=1&profile=advanced Both look for the same term, but it seems that there is bias on the Content namespace, and that this overrides the exact matching of the search term ?
