Hi, Everyone:
I just start studying lucene's source code.
I'm confused about those per-field formats, in this package of "
*org.apache.lucene.codecs.perfield*"
There are many formats in lucene's codec. But there are only 3 per-field
formats: "DocValues", "KnnVectors" and "Postings".
So, what is the purpose of those three per-field formats?
Why "DocValues", "KnnVectors" and "Postings" are so special that they need
those per-field formats?
For example, I've studied the "KnnVectors" a little.
The "PerFieldKnnVectorsFormat.FieldsWriter" acutally uses the
"Lucene94HnswVectorsFormat".
But why do we have this kind of structures?
Thanks & Regards
MyCoy
