Here is a snippet of the current StringIndex class:
public static class StringIndex {
/** All the term values, in natural order. */
public final String[] lookup;
/** For each document, an index into the lookup array. */
public final int[] order;
}
The order field is used for sorting within a single IndexSearcher, but
the lookup field is needed to populate the actual string value so it
may be used by MultiSearchers to order hits from multiple Searchers.
Look at FieldSortedHitQueue.comparatorString() for more info.
I guess it would be nice to have some way of telling the searcher (and
the fieldcache) whether the actual string values are needed or not...
it could save a lot of memory when there are a lot of unique terms.
