Hi
I need to access min and max values of a particular field in the index, as
soon as a searcher is initialized. I don't need it later. Looking at old
newsgroup mails, I found a few recommendations.
One was to keep the min and max fields external to the index. But this will
not work for us.
Then there was the recommendation to use FieldCacheImpl, as sorting might be
a little expensive. Looking at FieldCacheImpl implementation, I had a couple of
questions. Sorry if this has been asked and answered before.
If I use this method
// inherit javadocs
public String[] getStrings (IndexReader reader, String field)
The string array I get back, is it guaranteed that the first non-null value I
encounter in the array is the minimum value for this field and iterating
through the array in the reverse order, the first non-null value I encounter is
the max value for the field?
Thank you
