 The field should store a vector of values that

You can just add more than one field with the same name but different 
values per document, then searching for single values should work.

Hello Michael,

This is something you'd have to code on your own.

 Hi everybody,
 
 I am thinking about extending the Lucene search with metadata in the
 following way
 
 Field Value

---
 Title (n1, n2, n3, ..., nm) | ni element of {0,1} and m amount of
 distinct
 metadata values for title
 
 Expressed in an informal way, I want to store a tuple of values in a
 field.
 The values in the tuple show whether a value is used in the title or
 not.
 
 My question is then, whether I have to code that on my own or if the
 model
 is already set up to work like that.
 
 Thanks,
 Michael

A Lucene index can easily be used to determine whether or not a term is
in a field of a document:

IndexReader.open(indexName).termDocs(new Term(term, field)).skipTo(documentNr)

returns the boolean indicating that.
What do you need the {0,1} values for?

Paul Elschot.

Well, almost. When it returns true one still needs to check the TermDocs
for being at the documentNr.
