26 * Defines the contract for criteria used to perform lookups of workflow document data. None of the elements that can
27 * be defined on the criteria are required. Therefore, any method on this class may return a null value, though in the
28 * case of collections, an empty collection will be returned instead.
29 *
30 * <p>In general, the different values on the criteria allow the standard lookup "operators" as defined by
31 * {@link org.kuali.rice.core.api.search.SearchOperator} unless otherwise noted. The primary place where this differs
32 * is on principal name-based criteria (see below).</p>
33 *
34 * <p><On criteria which contains a principal name, the rules are as follows:</p>
35 *
36 * <ul>
37 * <li>only literal principal names that resolve to a valid principal are allowed</li>
38 * <li>however, if the principal names don't resolve to valid prinicpals, this simply means the lookup will return no results</li>
39 * <li>"!" is allowed before a principal name</li>
40 * <li>when wanting to search for more than one principal, "|" and "&&" is allowed though they cannot be used together</li>
41 * </ul>
42 *
43 * <p>Wildcards, ranges, and other "inequality" operators (such as ">", "<", etc.) are not permitted on principal names.</p>
44 *
45 * <p>In cases where a criteria element takes a list of values, this should be treated as an implicit "OR" by the lookup
46 * implementation. This is true of document attribute values as well, which are passed as a map keyed off the
47 * document attribute name with a list of values representing the document attribute values to be searched for.</p>
48 *
49 * <p>The optional "save name" on the search defines a name under which the criteria can be stored so that it can be
50 * recalled and reused later.</p>
