not supplied by the client, the following defaults are
applied at ADS:

Series fields
Relevance (value=102) for Title, Author
and Abstract fields
POSITION: -- Any (value=3)
STRUCTURE -- Date (value=5) for Publication Date field
Word list (value=6) for all other
TRUNCATION: -- Do not truncate (value=100)

Wild Card:
ADS supports wthe wildcard character '*' at the beginning and
the end of a word, but not within a word.
Helpful Hints:
1. Within a field, words are OR'd by default. This can be
changed by pre-fixing a word with a '+' to require that word in
the result, or by pre-fixing it with a '-' to select only
references that do not contain this word. Enclosing several
words in double quotes searches for the sequence of the words
in quotes.
