Examples of org.apache.lucene.search.FieldDoc

org.apache.lucene.search.FieldDoc
Expert: A ScoreDoc which also contains information about how to sort the referenced document. In addition to the document number and score, this object contains an array of values for the document from the field(s) used to sort. For example, if the sort criteria was to sort by fields "a", "b" then "c", the fields object array will have three elements, corresponding respectively to the term values for the document in fields "a", "b" and "c". The class of each element in the array will be either Integer, Float or String depending on the type of values in the terms of each field.
