Hi,
Thanks for the information. However, I still have one more problem. I am
iterating over the values of the NamedList. I have 2 values, one
being 'responseHeader' and the other one being 'grouped'. I would like to
access some information stored within the grouped section, which has
data structured like so:
grouped={attr_directory={matches=4,groups=[{groupValue=C:\Users\rvassallo\Desktop\Index,doclist={numFound=2,start=0,docs=[SolrDocument[{attr_meta=[Author,
kcook, Last-Modified, 2011-03-02T14:14:18Z...
With the 'get("group")' method I am only able to access the entire
'{attr_directory={matches=4,g...' section. Is there some functionality which
allows me to get other data? Something like this for instance:
'get("group.matches")' or maybe 'get(group.attr_directory.matches)' (which
will yield the value of 4), or do I need to process the String that the
'get("...")' returns to get what I need?
Thanks :)
