A question about FacetField constructor
Hello All:
I am building sample code using lucene v4.8.1 to explore
the new facet API. The problem I am having is that if I pass
a populated string array nothing gets indexed while if
I pass only the first element of the string array that value gets indexed.
The code found below shows the case that works and the case that does not
work. What am I doing wrong?
****************Start of code sample*************************
void showStuff( String... va )
{
/** This code permits out the contents of va successfully.**/
for( int ii = 0 ; ii < va.length ; ii++ )
System.out.println( "value[" + ii + "] " + va[ii] );
}
for( final Map< String, String[] > fd : allFacetData )
{
final Document doc = new Document();
for( final Map.Entry< String, String[] > entry :
fd.entrySet() )
{
final String key = entry.getKey();
String[] value = entry.getValue();
showStuff( value );
/** This call indexes successfully **/
final FacetField newFF = new FacetField(
key, value[0] );
/**
* This call will not index anything if
the value String array
* has more than one element.
*final FacetField newFF = new
FacetField( key, value );
*/
doc.add( newFF );
}
try
{
final Document theBuildDoc =
configFacetsHandle.
build( taxoWriter, doc );
indexWriter.addDocument( theBuildDoc );
indexWriter.addDocument(
configFacetsHandle.buil
d( taxoWriter, doc ) );
}
catch( IOException ioe )
{
eMsg.append( method );
eMsg.append( " failed with the exception "
);
eMsg.append( ioe.toString() );
return constantValuesInterface.FAILURE;
}
}
*******************End of code sample***************

Hello:
>What do you mean by does not index anything?
When I do a search the value returned for the "dim" set to "Publish Date"
is null. If I pass through value[0] the publish date year is returned by
the search.
setHierarchical was called.
When a String[] with more than one element is passed an exception is not
thrown.
I am open to all suggestions as to what I am missing.

What do you mean by does not index anything? Do you get an exception when
you add a String[] with more than one element?
You should probably call conf.setHierarchical(dimension), but if you don't
do that you should receive an IllegalArgumentException telling you to do
that...
