with the following command:

sh anserini/target/appassembler/bin/IndexCollection -collection JsonCollection \
  -generator DefaultLuceneDocumentGenerator -threads 22 \
  -input wikipedia-dpr-jsonl -index index-wikipedia-dpr-20210120-d1b9e6 -storeRaw -optimize

Note that to reduce index size:

+ document vectors are not stored (so no query expansion)

However, the raw documents are stored, so they can be fetched and fed to further downstream reranking components.
