During initial database creation the indices needed for searching are not
built. This will speed up the retrieval process. After the first
walking session, you need to tell gw
to create the search indices
with the -index
option. You will also need to give it the same option
to update the indices after any significant additions are made to the
database. Subsequent -index
commands will update the existing
indices, not rebuild them from scratch.
The database is always searchable, even if retrieval is in progress.
