+When installing Search::Xapian, make sure the underlying Xapian
+is patched against the index corruption bug documented in:
+
+	https://bugs.debian.org/808610
+
+For Debian 8.0, this means installing from jessie-backports
+until the fix lands in jessie.
+
+# Ensure the following line is in your apt sources.list(5)
+# (typically /etc/apt/sources.list):
+
+deb http://http.us.debian.org/debian jessie-backports main
+
+Then run:
+
+	apt-get update
+	apt-get install -t jessie-backports libxapian22
+
+to install the package.
+
+public-inbox will never store unregeneratable data in Xapian
+or any other search database we might use; Xapian corruption
+will not destroy critical data.
