=head1 NAME
-IDZebra::Session -
+IDZebra::Resultset - Representation of Zebra search results
=head1 SYNOPSIS
+ $count = $rs->count;
+
+ printf ("RS Status is %d (%s)\n", $rs->errCode, $rs->errString);
+
+ my @recs = $rs->records(from => 1,
+ to => 10);
+
=head1 DESCRIPTION
+The I<Resultset> object represents results of a Zebra search. Contains number of hits, search status, and can be used to sort and retrieve the records.
+
+=head1 PROPERTIES
+
+The folowing properties are available, trough object methods and the object hash reference:
+
+=over 4
+
+=item B<errCode>
+
+The error code returned from search, resulting the Resultset object.
+
+=item B<errString>
+
+The optional error string
+
+=item B<recordCount>
+
+The number of hits (records available) in the resultset
+
+=item B<count>
+
+Just the synonym for I<recordCount>
+
+=back
+
+=head1 RETRIEVING RECORDS
+
+In order to retrieve records, use the I<records> method:
+
+ my @recs = $rs->records();
+
+By default this is going to return an array of IDZebra::RetrievalRecord objects. The possible arguments are:
+
+=over 4
+
+=item B<from>
+
+Retrieve records from the given position. The first record corresponds to position 1. If not specified, retrieval starts from the first record.
+
+=item B<to>
+
+The last record position to be fetched. If not specified, all records are going to be fetched, starting from position I<from>.
+
+=item B<elementSet>
+
+The element set used for retrieval. If not specified 'I<R>' is used, which will return the "record" in the original format (ie.: without extraction, just as the original file, or data buffer in the update call).
+
+=item B<schema>
+
+The schema used for retrieval. The default is "".
+
+=item B<recordSyntax>
+
+The record syntax for retrieval. The default is SUTRS.
