Query operators

New letters in inbox

• in:inbox is:unread

Time related

• Today --> after:yesterday (Due to the search "after:today" was not completed to cover all emails today, I suggest you use after:yesterday)
• Last Week --> after:oneweekago

Focus some labels / Cluster with some labels

• My Focus --> (label:label_a OR label:label_b)

focus on the letters with the labels: label_a or label_b

• My Focus (new) --> (label:label_a OR label:label_b) is:unread

focus on the new letters with the labels: label_a or label_b

filter emails with multiple labels

• Search label:label_a label:label_b to filter the emails matched multiple labels

search for all emails with no label 只看沒編過標籤的信

• 列出所有標籤，然後再排除它們(參考資料)：搜尋語法是 -label:標籤名稱1 -label:標籤名稱2 -label:標籤名稱3
• 如果標籤已經很多，就顯得很麻煩

不支援部分字串搜尋

• 搜尋結果不包括部分字串相符的項目，或與查詢條件「類似」的項目。資料來源: 內收郵件未送達 - Gmail說明(test day: 2011-11-11)
