Problem with Field.Keyword
We are developing application that indexes email using Lucene. To index
document we use the message id field of the email as the primary key.
The message id field looks like:
<02...@host86.syd.nuix.com.au>
<81...@excsrv44.mayo.edu>
<3D...@mail.totalise.co.uk>
We store this message id as Field.Keyword.
Unfortunately when we are storing the message id, searching and deleting of
documents (very important for us) doesn't work.
*If* the message id is stored as Field.Text it will work for searching but
not _deletion_.
I'm 100% the code works because as soon as I substitute the message id into
ordinary number such as 1, 2, 3 everything works as coded :D
Any suggestions?

That is what I thought as well. As soon as I changed the message id into an
internal id that I generated myself everything works. Must be something
strange with the format of the message id.

I am a little unclear,
When you index do you store
> <02...@host86.syd.nuix.com.au>
> <81...@excsrv44.mayo.edu>
> <3D...@mail.totalise.co.uk>
Or
<3D...@mail.totalise.co.uk>
The reason why I ask is that Keyword does not tokenize (that is what ever
you put into that field is seen as a single term).
So if you want to find it you have to search for exactly what you typed in
(including case sensitive).
Does that help?

Hmm not quite my problem here.

OK .. let me try again ...
basically I have a field in the document which I derive from the message id
of an email, they look like:
<02...@host86.syd.nuix.com.au>
<81...@excsrv44.mayo.edu>
<3D...@mail.totalise.co.uk>
The problem is that I couldn't search Lucene using this field. If I store
this field as Text I can search and find the document but I couldn't delete
it using the following:
indexReader.delete(new Term("id", "<3D...@mail.totalise.co.uk>");
This will return 0.
If I store the id as a keyword, I couldn't even search the field.
