the following code has a bug of StringIndexOutofBounds when multiple matched
terms need highlight
private String makeFragment( WeightedFragInfo fragInfo, String src, int s,
String[] preTags, String[] postTags, Encoder encoder ){
StringBuilder fragment = new StringBuilder();
int srcIndex = 0;
for( SubInfo subInfo : fragInfo.subInfos ){
for( Toffs to : subInfo.termsOffsets ){
fragment
.append( encoder.encodeText( src.substring( srcIndex,
to.startOffset - s ) ) )
.append( getPreTag( preTags, subInfo.seqnum ) )
.append( encoder.encodeText( src.substring( to.startOffset - s,
to.endOffset - s ) ) )
.append( getPostTag( postTags, subInfo.seqnum ) );
srcIndex = to.endOffset - s;
}
}
fragment.append( encoder.encodeText( src.substring( srcIndex ) ) );
return fragment.toString();
