- `REPO_INDEXER_PATH`: **indexers/repos.bleve**: Index file used for code search.
- `UPDATE_BUFFER_LEN`: **20**: Buffer length of index request.
- `MAX_FILE_SIZE`: **1048576**: Maximum size in bytes of files to be indexed.
- `REPO_INDEXER_CAMEL_CASE`: **true**: When `REPO_INDEXER_CAMEL_CASE` is true, repository indexer will break camel case into words, so thisCameCaseName will be indexed as this, camel, case, name. It's imperative to delete any previous indexes from REPO_INDEXER_PATH after changing this setting.
