The FindQualifier interface defines constants that are used when performing registry search operations to specify criteria such has how to combine multiple keys, whether the operation should consider case, and whether the results should be sorted. Registry providers are required to implement all qualifiers, apart from SOUNDEX, while non-UDDI providers are not required to implement SERVICE_SUBSET and COMBINE_CLASSIFICATIONS.
