From 525555d14118f92f86be54c683f797089c52a78d Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sat, 5 Dec 2020 10:11:38 +0000 Subject: isearch: emulate per-inbox search with ->ALL Using "eidx_key:" boolean prefix to limit results to a given inbox, we can use ->ALL to emulate and replace per-Inbox xap15/[0-9] search indices. With this change, the presence of "extindex.all.topdir" in the $PI_CONFIG will cause the WWW code to use that extindex and ignore per-inbox Xapian DBs in xap15/[0-9]. Unfortunately IMAP search still requires old per-inbox indices, for now. Mapping extindex Xapian docids to per-Inbox UIDs and vice-versa is proving tricky. Fortunately, IMAP search is rarely used and optional. The RFCs don't specify expensive phrase search, either, so `indexlevel=medium' can be used in per-inbox Xapian indices to save space. For primarily WWW (and future JMAP) users; this should result in significant disk space, FD, and page cache footprint savings for large instances with many inboxes and many cross-posted messages. --- lib/PublicInbox/WwwText.pm | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/PublicInbox/WwwText.pm') diff --git a/lib/PublicInbox/WwwText.pm b/lib/PublicInbox/WwwText.pm index 04c9b1c4..8cc818df 100644 --- a/lib/PublicInbox/WwwText.pm +++ b/lib/PublicInbox/WwwText.pm @@ -250,7 +250,7 @@ EOF # n.b. we use the Xapian DB for any regeneratable, # order-of-arrival-independent data. - my $srch = $ibx->search; + my $srch = $ibx->isrch; if ($srch) { $$txt .= <
