Yeah, for id my plan was just let the user supply the field, perhaps default to
id. The other issue is that we hash on the indexed value though - which we get
though a customizable field type method impl last I recall. I think this tends
to be the same as the raw text for the types we care about. But we have to make
some assumptions - it's not really arbitrary support - though it should easily
cover the current common types of numeric or string. I think most impls end up
using UnicodeUtil.UTF16toUTF8 and hopefully most toInternal methods simply
return what is passed in (ie use the base class impl)...
/** Given an indexed term, append the human readable representation*/
public CharsRef indexedToReadable(BytesRef input, CharsRef output) {
UnicodeUtil.UTF8toUTF16(input, output);
return output;
}
public String toInternal(String val) {
// - used in delete when a Term needs to be created.
// - used by the default getTokenizer() and createField()
return val;
}
