Yes, I saw that code. However, I thought it is intended for use when merging
multiple segments into one, field by field.
May I share a simple example to explain why I think so? Let's say we have
the following example:
```java
var logger = LogManager.getLogger("lucene_index");
var infoStream = new Log4j2InfoStream(logger, Level.toLevel("info"));
var out = FSDirectory.open(Path.of("/home/sherman/experiments7/"));
var cfg = new IndexWriterConfig();
cfg.setUseCompoundFile(false);
var indexWriter = new IndexWriter(out, cfg);
for (var i = 0; i < 10000; i++) {
var doc = new Document();
doc.add(new SortedSetDocValuesField("field1", new BytesRef("term1_" +
i)));
if (i < 500) {
doc.add(new SortedSetDocValuesField("field2", new BytesRef("term1_"
+ i)));
}
indexWriter.addDocument(doc);
}
indexWriter.close();
```
In this example, each field has its own term dictionary, because I see two
calls of [addTermsDict()
method](https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/codecs/lucene90/Lucene90DocValuesConsumer.java#L544).
I think I need to conduct further investigation to create a prototype that
can produce the same files as a result.
Maybe, I missed something.
