-To force the indexer to include specific files (like `yarn.lock` or other large text files) that are otherwise skipped, add their file path or a glob pattern to the [`search.largeFiles`](/admin/config/site_config#search-largeFiles) setting in your site configuration and reindex the repository.

 For large deployments we recommend horizontally scaling indexed search. You can do this by [adjusting the number of replicas](https://github.com/sourcegraph/deploy-sourcegraph/blob/master/docs/configure#configure-indexed-search-replica-count). Sourcegraph shards repository indexes across replicas. When the replica count changes Sourcegraph will slowly rebalance indexes to ensure availability of existing indexes.
