I don't, but at one point this worked:


load [file join "/s1/james/local/lib/tcl8.3" xapian.so]
set db [xapian::open
xapian::Enquire enq $db
xapian::Query qu "wibbl"
enq set_query qu
# We now have an Enquire object on our database, so should be able
# to get the MSet (the set of matches) from that - we'll get the
# first ten matches:
set mset [enq get_mset 0 10]
set mi [$mset begin]
while { ! [$mi equals [$mset end]] } {
    puts -nonewline "ID "
    puts -nonewline [$mi get_docid]
    puts -nonewline " "
    puts -nonewline [$mi get_percent]
    puts -nonewline " "
    puts [[$mi get_document] get_data]
    $mi next

However it doesn't now - the xapian:: prefix has disappeared from the
wrapper. Assuming you're using --enable-maintainer-mode, applying the
following patch to xapian-bindings/tcl8/Makefile.am will work:

Or Postgresql supports both Perl and Python these days, for which
there are reasonable wrappers. (If the Python ones lack anything
that's useful to you, I should be able to add it fairly quickly - I
think Perl is reasonably up to date, but can't really speak for it.)
