 +Metasearch, parallel search(平行檢索),​ federated search(聯合檢索),​ broadcast search(廣播檢索),​ cross-database search(跨 資料庫檢索),​ search portal(檢索入口) 在資訊社群的詞彙中都有相同的部份。 它們都是指一次能同時能檢索多種資料庫、來源、平台、通信協定與內容提供者。目前 Metasearch 有許多作法,包括了公開的標準(如 NISO Z39.50),services rely on a variety of approaches to search and retrieval including open standards (such as NISO's Z39.50), 專屬的API,與screen scraping(抓取頁面資料)。然而,由於缺乏廣泛接受的標準,實做範例,與工具,使得metasearch環境,不論對使用者、系統提供者、與內容提供者而言,都很沒有效率。

 +此Metasearch協定期望達到:
 +* 使metasearch系統能提供更有效率與即時的服務 service providers to offer more effective and responsive services
 +* 內容提供者能提供更豐富的內容且保護其智慧財產 content providers to deliver enhanced content and protect their intellectual property
 +* 圖書館能提供其他網路服務所提供的內容 libraries to deliver services that distinguish their services from Google and other free web services.
