From c23df198cb3b101c8f0ede73092c8f3dae5eda35 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 16 May 2019 03:40:47 +0000 Subject: [PATCH] search: disable phrase searching, for now There probably needs to be an option to enable this independently of indexlevel; but for now this is the safest option. And, as I discovered during the development of the indexlevel option, Xapian does a pretty good job of finding phrases without position data, anyways. --- lib/PublicInbox/Search.pm | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lib/PublicInbox/Search.pm b/lib/PublicInbox/Search.pm index 090d998b..bb4bd454 100644 --- a/lib/PublicInbox/Search.pm +++ b/lib/PublicInbox/Search.pm @@ -45,7 +45,11 @@ use constant { # n.b.
