Reassembling split indices
The large dense indices (the three full Wikipedia ones and the partial Wikipedia Qwen3-Embedding-4B one) are stored as 45 GB chunks. Concatenate the parts in order before use:
cat bge_Flat.index.part_* > bge_Flat.index
cat e5_Flat.index.part_* > e5_Flat.index
cat contriever_Flat.index.part_* > contriever_Flat.index
cat qwen3_emb_4b_Flat.index.part_* > qwen3_emb_4b_Flat.index
cat with a shell glob sorts the suffixes (part_aa, part_ab, …) correctly.
All other indices are ready to use as-is.
