Subject Re: [jira] Created: (COUCHDB-74) CouchDB full text searching
Date Fri, 30 May 2008 21:40:20 GMT
Noticed a couple errors in that:

davisp@nebula:/usr/local/src/tmp/couchdb-lucene$ tar -cvf
couchdb-xapian.tar.gz couchdb-xapian/

should be

davisp@nebula:/usr/local/src/tmp/couchdb-lucene$ tar -cvzf
couchdb-xapian.tar.gz couchdb-xapian/

And xapian.conf is in /path/to/couchdb-xapian/

I think that's it.
