Requirements and Defaults: The Use attribute is REQUIRED. For the other attributes, if an attribute type and value are not supplied by the client, the following defaults are applied at ADS: RELATION: -- Equal (value=3) for Publication Date and 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) COMPLETENESS: -- Incomplete subfield (value=1)
Phrase searches (title, abstract): Phrase search terms can appear anywhere in the field. 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.
