Xapian discuss - Nov 2009 - [python indexer] add meta informations

Hello,

I'm trying to index some blog stuff through python bindings.

I'd like to know how to add some informations (url, title, date, and so on)
so that I can reach them through a xapian.Enquire object..
I believe it's something to be set in xapian.TermGenerator(), but... I
can't manage to find which function. I'm waiting for something like :
xtermgen.add_meta('url', 'value')

but.. well, as you imagine, I can't find which function to use.

Thanks in advance

C. Jeanneret



PS: I prefere not to use scriptindex nor omega, as it's all in a pylon
application...

Hi Cedric,

Since you're using Python, you might want to take a look at Xappy,
which provides a higher-level interface to Xapian and lets you work
with named fields rather than terms etc.

Tom

At index time, serialise the data you want to store to get a string (in Python,
you'd probably just pickle it) and the store it with Document.set_data().

Then at search time, you unpickle the string retrieved by get_data() on the
Document object.
