This topic presents some approaches to solving sorting problems.
If the returned records do not seem to respect
the sort key parameter, there are some potential problems:
- Was the attribute specified
as numeric when it is actually alphanumeric? Or vice versa? In this case,
Endeca Server returns a valid response, but the sorting may be incorrect.
- If a record has multiple
attribute value assignments from a single attribute, Endeca Server sorts the
records based on the first value associated with the key. If the application is
displaying the last value, the records will not appear to be sorted correctly.
In general, attributes that are used for sorting should only have one value
assigned per record.
- If certain records in a data
domain lack a sort-key value, they will always appear last in a result set.
Therefore, if you reverse a sort order on a record set containing such records,
the order of the entire record set will not be reversed — the records without a
sort key value always sort at the end of the set.
