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/ExtSearch.pm | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/PublicInbox/ExtSearch.pm') diff --git a/lib/PublicInbox/ExtSearch.pm b/lib/PublicInbox/ExtSearch.pm index 80455d8d..2a560935 100644 --- a/lib/PublicInbox/ExtSearch.pm +++ b/lib/PublicInbox/ExtSearch.pm @@ -128,5 +128,6 @@ no warnings 'once'; *recent = \&PublicInbox::Inbox::recent; *max_git_epoch = *nntp_usable = *msg_by_path = \&mm; # undef +*isrch = *search; 1; -- cgit v1.2.3-24-ge0c7
