Interesting.  That's either a bug or a feature Jose put in that I
didn't see.

-u was suppose to only "add" words to an index, and indeed it does do
exactly that if you dump the index:

    moseley@bumby:~/swish-e$ echo "foo bar baz" > file
    moseley@bumby:~/swish-e$ src/swish-e -v0 -i file
    moseley@bumby:~/swish-e$ src/swish-e -T index_words

    -----> WORD INFO in index index.swish-e <-----

    bar [1 1 1 (6/9)]

    baz [1 1 1 (7/9)]

    foo [1 1 1 (5/9)]

    moseley@bumby:~/swish-e$ echo "bar baz" > file
    moseley@bumby:~/swish-e$ src/swish-e -v0 -i file -u
    moseley@bumby:~/swish-e$ src/swish-e -T index_words

    -----> WORD INFO in index index.swish-e <-----

    bar [1 1 1 (6/9)] [1 2 1 (5/9)]

    baz [1 1 1 (7/9)] [1 2 1 (6/9)]

    foo [1 1 1 (5/9)]

So "foo" is still in the index.  But, as you say:

    moseley@bumby:~/swish-e$ src/swish-e -w foo
    # SWISH format: 2.5.1
    # Search words: foo
    # Removed stopwords: 
    err: no results
    .

So is that a bug or a feature?  Have to wait for Jose to get back from
vacation -- which might be the entire month of August!
