Modifier and Type	Method and Description
abstract BitSet	Filter.bits(IndexReader reader) Returns a BitSet with true for documents which should be permitted in search results, and false for those that should not.
Explanation	Weight.explain(IndexReader reader, int doc) An explanation of the score computation for the named document.
Object	FieldCache.getAuto(IndexReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found reads field to see if it contains integers, floats or strings, and then calls one of the other methods in this class to get the values.
Comparable[]	FieldCache.getCustom(IndexReader reader, String field, SortComparator comparator) Checks the internal cache for an appropriate entry, and if none is found reads the terms out of field and calls the given SortComparator to get the sort values.
float[]	FieldCache.getFloats(IndexReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as floats and returns an array of size reader.maxDoc() of the value each document has in the given field.
int[]	FieldCache.getInts(IndexReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as integers and returns an array of size reader.maxDoc() of the value each document has in the given field.
FieldCache.StringIndex	FieldCache.getStringIndex(IndexReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found reads the term values in field and returns an array of them in natural order, along with an array telling which element in the term array each document uses.
String[]	FieldCache.getStrings(IndexReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the term values in field and returns an array of size reader.maxDoc() containing the value each document has in the given field.
