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