$qh - search results

From 6ffa9c19e710ee2ece98a987477e9c5baaca13cd Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sat, 12 Sep 2015 01:23:32 +0000 Subject: searchview: support displaying entire threads This hopefully makes it easy to perform queries to display an entire thread. Raise the limit in the threaded view to display more results and hopefully improve the output of thread display. --- lib/PublicInbox/SearchView.pm | 239 ++++++++++++++++++++++++++++++++++-------- 1 file changed, 193 insertions(+), 46 deletions(-) (limited to 'lib/PublicInbox/SearchView.pm') diff --git a/lib/PublicInbox/SearchView.pm b/lib/PublicInbox/SearchView.pm index 82b97f32..c15a0463 100644 --- a/lib/PublicInbox/SearchView.pm +++ b/lib/PublicInbox/SearchView.pm @@ -6,52 +6,49 @@ use warnings; use PublicInbox::SearchMsg; use PublicInbox::Hval; use PublicInbox::View; +use PublicInbox::MID qw(mid2path mid_clean); +use Email::MIME; use POSIX qw/strftime/; -our $LIM = 25; +our $LIM = 50; sub sres_top_html { - my ($ctx, $q) = @_; - my $cgi = $ctx->{cgi}; + my ($ctx) = @_; + my $q = PublicInbox::SearchQuery->new($ctx->{cgi}); my $code = 200; - # $q ||= $cgi->param('q'); - my $o = int($cgi->param('o') || 0); - my $r = $cgi->param('r'); - $r = (defined $r && $r ne '0'); - my $opts = { limit => $LIM, offset => $o, mset => 1, relevance => $r }; + + # double the limit for expanded views: + my $opts = { + limit => $LIM, + offset => $q->{o}, + mset => 1, + relevance => $q->{r}, + }; my ($mset, $total); + eval { - $mset = $ctx->{srch}->query($q, $opts); + $mset = $ctx->{srch}->query($q->{q}, $opts); $total = $mset->get_matches_estimated; }; my $err = $@; - my $query = PublicInbox::Hval->new_oneline($q); - my $qh = $query->as_html; - my $res = "$qh - search results" . - qq{} . - qq{}; - - $res .= qq{} if $r; - - $res .= qq{} . - PublicInbox::View::PRE_WRAP; - - my $foot = $ctx->{footer} || ''; - $foot = qq{Back to index.}; + my $res = html_start($q) .
