+  Create and update search indices
+
+options:
+
+  --no-fsync          speed up indexing, risk corruption on power outage
+  -L LEVEL            `basic', `medium', or `full' (default: full)
+  --all               index all configured inboxes
+  --compact | -c      run public-inbox-compact(1) after indexing
+  --sequential-shard  index Xapian shards sequentially for slow storage
+  --jobs=NUM          set or disable parallelization (NUM=0)
+  --batch-size=BYTES  flush changes to OS after a given number of bytes
+  --max-size=BYTES    do not index messages larger than the given size
+  --reindex           index previously indexed data (if upgrading)
+  --rethread          regenerate thread IDs (if upgrading, use sparingly)
+  --prune             prune git storage on discontiguous history
+  --verbose | -v      increase verbosity (may be repeated)
+
+BYTES may use `k', `m', and `g' suffixes (e.g. `10m' for 10 megabytes)
+See public-inbox-index(1) man page for full documentation.
