Right, this is what I think as well. So in the case of web caching,
you may have a byte[] and some metadata (K/V pairs), but what you
would cache is probably a custom object of yours- something like:
MIMEObject {
@Indexed String mimeType;
byte[] content;
}
I guess the tricky bit would be representing an arbitrary-length
dictionary of metadata as indexable fields? Is this what you are
getting at, Mic?
you can index Maps and use a custom bridge to map a String key to a
field in lucene. This is fairly standard HSearch procedure.
BTW your example should read
@Indexed @ProvidedId
class MIMEObject {
@Field String mimeType;
byte[] content;
}
