Xapian wiki: typo in docid to sub-db translation?
On the Xapian wiki page:
http://trac.xapian.org/wiki/FAQ/MultiDatabaseDocumentID
It seems to me that:
subdatabase_number = docid_combined % number_of_databases;
Should read:
subdatabase_number = (docid_combined - 1) % number_of_databases;
Otherwise I'm seriously confused ...
Cheers,
jf

stub-file and get_doccount
Hello,
i switched from one big index to a stub file with many indexes and running
into a problem.
i have a tool to fetch a random document via:
get_doccount
random id up to get_doccount
get_document with that id
after changing to stub file this failes. Is there a nice way to get a
random document from a stub file?
?MfG?

overlapping docids when searching on multiple databases?
Just a quick question - it seems to me that it's entirely possible to
get overlapping docids when searching on multiple databases? For
instance:
open database1
add database2 to database1
search db1+db2
if docid 10 exists in both databases, is there any way of telling which
which database to retrieve the document from?

Yes: https://trac.xapian.org/wiki/FAQ/MultiDatabaseDocumentID
1.4.12 added a Database::size() method which reports the number of
shards - for older versions you have to keep track of that yourself
(which needs a little care as add_database() "flattens", so after
db1.add_database(db2) db1.size() will have increased by db2.size()
(which could be 0 if...
