Subject [jira] [Commented] (LUCENE-4820) Add optional payload to AnalyzingSuggester
Date Thu, 14 Mar 2013 22:26:13 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4820?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602832#comment-13602832

Robert Muir commented on LUCENE-4820:
-------------------------------------

Wouldn't it be better if the payload was an additional FST output (e.g. in the case its an
ID or something).

Its wierd its tacked onto the surface form with INFORMATION_SEPARATOR.

I havent fully thought about the benefits, but i guess an ID value as a separate output could
be used for
other things, like participating in the top-N comparator to simplify the tie-break logic (which
if i recall,
is super-hairy for this suggester).

It might also be more efficient as a separate output, but I havent thought about all the cases
there either.
its like if payloads dont exist we could just use the empty string or whatever and there is
really not much
added cost.
