> FastVectorHighlighter: add a method to set an arbitrary char that is used when concatenating multiValued data
> -------------------------------------------------------------------------------------------------------------
>
> Key: LUCENE-2603
> URL: https://issues.apache.org/jira/browse/LUCENE-2603
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/highlighter
> Affects Versions: 2.9.3, 3.0.2
> Reporter: Koji Sekiguchi
> Assignee: Koji Sekiguchi
> Priority: Trivial
> Fix For: 3.1, 4.0
>
> Attachments: LUCENE-2603.patch, LUCENE-2603.patch

>
> If the following multiValued names are in authors field:
> * Michael McCandless
> * Erik Hatcher
> * Otis Gospodnetić
> Since FragmentsBuilder concatenates multiValued data with a space in BaseFragmentsBuilder.getFragmentSource():
> {code}
> while( buffer.length() < endOffset && index[0] < values.length ){
> if( index[0] > 0 && values[index[0]].isTokenized() && values[index[0]].stringValue().length() > 0 )
> buffer.append( ' ' );
> buffer.append( values[index[0]++].stringValue() );
> }
> {code}
> an entire field snippet (using LUCENE-2464) will be "Michael McCandless Erik Hatcher Otis Gospodnetić". There is a requirement an arbitrary char (e.g. '/') can be set so that client can separate the snippet easily. i.e. "Michael McCandless/Erik Hatcher/Otis Gospodnetić"
