I had a look at Beagle to see what it does. It allows the index to
store multiple data items for each keyword. For example from the email
filter:
using (GMime.InternetAddressList addrs = this.message.GetRecipients (GMime.RecipientType.To)) {
foreach (GMime.InternetAddress ia in addrs)
AddProperty (Property.NewKeyword ("fixme:to", ia.ToString ());
}
}
Note how each person listed in the To: field of the email is added to
the index as a separate entry, so that searches like "receipient ends
with foo.com" would work correctly. The same feature would allow
multiple artists per song and so on.
I do wonder why nobody has taken a fast database-backed RDF triple store
(from librdf), put a sparql-based frontend on it for queries (again from
librdf) and used re-used a lot of code from both Beagle and Tracker for
harvesting the metadata...
