Multiple Projects

Each CodeIndexer instance is fully isolated — separate database, separate watcher. Run as many as you need in the same process:

const [frontend, backend] = await Promise.all([
  (async () => {
    const idx = new CodeIndexer({ projectRoot: '/repos/frontend' });
    await idx.initialize();
    await idx.indexProject();
    return idx;
  })(),
  (async () => {
    const idx = new CodeIndexer({ projectRoot: '/repos/backend' });
    await idx.initialize();
    await idx.indexProject();
    return idx;
  })(),
]);

const frontendResults = await frontend.search('React component');
const backendResults  = await backend.search('authentication handler');

Each instance stores its index at <projectRoot>/.lucerna by default. Use storageDir to override if needed.
