+Hi,
+
+I'm trying to set up a personal wiki and I'm having trouble getting
+search to work.  All my searches give zero results.  I eventually
+figured out that the Xapian database that's being created has an empty
+postlist table.  The position and termlist tables are all fine, and
+when I add new content to the wiki I can see the database is updated
+and the search terms are in the position table in plaintext.  But I
+can't query for them, even using Xapian's command line tools.

+
+I don't know how to debug from here.  Clearly ikiwiki is doing
+something right when it's building the database, but one of the tables
+is missing.  Can anyone guess what's wrong, or tell me where to start
+troubleshooting?

+I'm using Centos 5.  Xapian is version 1.2.5.  Ikiwiki version 3.20111107.
