Re: Search problem on no2.php.net

Hi,

Someone just pointed out to me that my mirror (no2.php.net) has some search problems. If you search for "for" on my mirror you end up on /manual/en/ref.var.php, not /manual/en/control-structures.for.php as you do on other mirrors. Anyone know why this might happen? The apache config is exactly as the one noted on the mirroring-page, and I've disabled the "var"-handler (I'm running Apache 2).

Interesting... Do you have the sqlite extension set up? I researched this problem, this is what happens:

- Must be using the sqlite lookup for this to occur. It does not occur using find_manual_page_slow() - a ref.* prefix has a search priority of 0 - a control-structures.* prefix has a search priority of 4 - The lower priority the better - As you can see just from this, "ref.var" supercedes "control-structures.for", but this isn't the problem, as "var" shouldn't be matching "for" in the first place. - metaphone("var") is "FR" - metaphone("for") is "FR" - metaphone matches get a worse priority, the problem? The priority they get is +1 of their usual priority, this means: - ref.var has a search priority of 0+1=1 for the search term "for" - control-structures.for has a search priority of 4+1=5 for the search term "for" - Thus, ref.var is returned when searching for "for". To fix it, instead of doing +1 for metaphone matches, how about doing +10? Then everything that's not metaphone is returned first and metaphone becomes a last resort? More testing might be needed.
