Hi Erick,
Thanks for your input. I have 2 annotation fields (Sorry, I don't have
access to the code at the moment to paste in).
but basically, I am sorting on an un-tokenized field.
The problem I have is that I am using wildcard queries, & from what I
believe they don't get the filters applied from the Analyzer that I have
defined.
By implementing a SortComparator I was able to sort correctly, however, if
there were some empty values, then a NullPointerException would be thrown.
After reading through the mailing list I see other people have had this
problem but I couldn't find a solution.
Does anybody know of a solution to stop the NullPointerException being
thrown when some of the fields dont have values for a custom SortComparator?
Thanks in advance,
Kevin.
