How to use TermVector Lucene 4.0

I had the same problem, so I just simply created my own Field:

public class VecTextField extends Field {

/* Indexed, tokenized, not stored. */
public static final FieldType TYPE_NOT_STORED = new FieldType();

/* Indexed, tokenized, stored. */
public static final FieldType TYPE_STORED = new FieldType();

static {
    TYPE_NOT_STORED.setIndexed(true);
    TYPE_NOT_STORED.setTokenized(true);
    TYPE_NOT_STORED.setStoreTermVectors(true);
    TYPE_NOT_STORED.setStoreTermVectorPositions(true);
    TYPE_NOT_STORED.freeze();

    TYPE_STORED.setIndexed(true);
    TYPE_STORED.setTokenized(true);
    TYPE_STORED.setStored(true);
    TYPE_STORED.setStoreTermVectors(true);
    TYPE_STORED.setStoreTermVectorPositions(true);
    TYPE_STORED.freeze();
}

// TODO: add sugar for term vectors...?

/** Creates a new TextField with Reader value. */
public VecTextField(String name, Reader reader, Store store) {
    super(name, reader, store == Store.YES ? TYPE_STORED : TYPE_NOT_STORED);
}

/** Creates a new TextField with String value. */
public VecTextField(String name, String value, Store store) {
    super(name, value, store == Store.YES ? TYPE_STORED : TYPE_NOT_STORED);
}

/** Creates a new un-stored TextField with TokenStream value. */
public VecTextField(String name, TokenStream stream) {
    super(name, stream, TYPE_NOT_STORED);
}

}

Hope this helps

TextField is a convenience class for users who need indexed fields without term vectors. If you need terms vectors, just use a Field. It takes a few more lines of code since you need to create an instance of FieldType first, set storeTermVectors and tokenizer to true and then use this FieldType instance in Field constructor.
