Nevertheless, searching for pages works as expected, as far as I can tell.

+Have you upgraded hyperestradier since setting up the wiki? Apparently it
+breaks a lot when it's upgraded, I find I often have to re-run ikiwiki
+-setup after upgrading hyperestradier to force it to rebuilt its database,
+then incremental updates work again for a while. This is one of the reasons
+I want to change to a different search backend. --[[Joey]]
+
+It was a completely fresh, completely untouched, unconfigured installation
+of hyperestrainer (Debian unstable on hurd-i386).
+Even when running an `ikiwiki --setup [...] --rebuild` I get this:
+
+ [...]
+ rendering templates/note.mdwn
+ rendering templates/popup.mdwn
+ updating hyperestraier search index
+ estcmd: ERROR: /home/wiki/wiki/.ikiwiki/hyperestraier: database problem
+ estcmd gather -cm -bc -cl -sd -cl /home/wiki/wiki/.ikiwiki/hyperestraier - exited nonzero: 256
+ done
+
+Now I did a `rm -rf ~wiki/wiki/.ikiwiki/hyperestraier` and re-ran
+`ikiwiki --setup [...] --rebuild`:
+
+ [...]
+ rendering templates/note.mdwn
+ rendering templates/popup.mdwn
+ updating hyperestraier search index
+ estcmd: ERROR: /home/wiki/wiki/.ikiwiki/hyperestraier: database problem
+ $ echo $?
+ 141
+
+`--rebuild`ing once more, I'm back to the previous error message.
