Indexing

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.
