## Indexer (`indexer`)
- `ISSUE_INDEXER_TYPE`: **bleve**: Issue indexer type, currently support: bleve or db, if it's db, below issue indexer item will be invalid.
- `ISSUE_INDEXER_PATH`: **indexers/issues.bleve**: Index file used for issue search.
- `ISSUE_INDEXER_QUEUE_TYPE`: **levelqueue**: Issue indexer queue, currently support: channel or levelqueue
- `ISSUE_INDEXER_QUEUE_DIR`: **indexers/issues.queue**: When ISSUE_INDEXER_QUEUE_TYPE is levelqueue, this will be the queue will be saved path
- `ISSUE_INDEXER_QUEUE_BATCH_NUMBER`: **20**: Batch queue number
- `REPO_INDEXER_ENABLED`: **false**: Enables code search (uses a lot of disk space).
- `REPO_INDEXER_PATH`: **indexers/repos.bleve**: Index file used for code search.
- `UPDATE_BUFFER_LEN`: **20**: Buffer length of index request.

- `PATH`: Tidb 或者 SQLite3 数据文件存放路径。
- `LOG_SQL`: **true**: 显示生成的SQL默认为真。
## Indexer (`indexer`)
- `ISSUE_INDEXER_TYPE`: **bleve**: 工单索引类型,当前支持 `bleve``db`,当为 `db` 时其它工单索引项可不用设置。
- `ISSUE_INDEXER_PATH`: **indexers/issues.bleve**: 工单索引文件存放路径,当索引类型为 `bleve` 时有效。
- `ISSUE_INDEXER_QUEUE_TYPE`: **levelqueue**: 工单索引队列类型,当前支持 `channel``levelqueue`
- `ISSUE_INDEXER_QUEUE_DIR`: **indexers/issues.queue**: 当 `ISSUE_INDEXER_QUEUE_TYPE``levelqueue` 时,保存索引队列的磁盘路径。
- `ISSUE_INDEXER_QUEUE_BATCH_NUMBER`: **20**: 队列处理中批量提交数量。
- `REPO_INDEXER_ENABLED`: **false**: 是否启用代码搜索(启用后会占用比较大的磁盘空间)。
- `REPO_INDEXER_PATH`: **indexers/repos.bleve**: 用于代码搜索的索引文件路径。
- `UPDATE_BUFFER_LEN`: **20**: 代码索引请求的缓冲区长度。
- `MAX_FILE_SIZE`: **1048576**: 进行解析的源代码文件的最大长度,小于该值时才会索引。
## Security (`security`)
- `INSTALL_LOCK`: 是否允许运行安装向导,(跟管理员账号有关,十分重要)。
