Hi:
Is there some way to read only 1 field value from an index given a docID?
From the current API, in order to get a field from given a docID, I
would call:
IndexSearcher.document(docID)
which in turn reads in all fields from the disk.
Here is my problem:
After the search, I have a set of docIDs. For each
document, I have a unique string identifier. At this point I only need
these identifiers but with the above API, I am forced to read the
entire row of fields for each document in the search result, which in
my case can be very large.
Is there an alternative?
I am thinking more on the lines of a call:
Field[] getFields(int docID,String fieldName);
Thanks
-John
