/**
|
|
* 对话系统消息索引
|
|
*
|
|
* 使用方法:
|
|
*
|
|
* 1. 索引管理
|
|
* - 创建索引: ZincSearchUserMsg::generateIndex();
|
|
* - 检查索引: ZincSearchBase::indexExists(ZincSearchUserMsg::$indexName);
|
|
* - 清空索引: ZincSearchUserMsg::clear();
|
|
*
|
|
* 2. 会话用户操作
|
|
* - 单个同步: ZincSearchUserMsg::syncUser($dialogUser);
|
|
* - 批量同步: ZincSearchUserMsg::batchSyncUsers($dialogUsers);
|
|
* - 删除用户: ZincSearchUserMsg::deleteUser($dialogUser);
|
|
*
|
|
* 3. 会话消息操作
|
|
* - 单个同步: ZincSearchUserMsg::syncMsg($dialogMsg);
|
|
* - 批量同步: ZincSearchUserMsg::batchSyncMsgs($dialogMsgs);
|
|
* - 删除消息: ZincSearchUserMsg::deleteMsg($dialogMsg);
|
|
*
|
|
* 4. 搜索功能
|
|
* - 关键词搜索: ZincSearchUserMsg::searchByKeyword('用户ID', '关键词');
