What is Hashtag Search?

By adding hashtags like #important or #quote to your reading notes, you can quickly search and filter related memos later. Only books containing memos with the specified tag will be displayed, making it easy to access the information you need even as your reading notes grow.

Allowed Characters

Tag names can include Japanese characters (hiragana, katakana, kanji), letters, and numbers.
Spaces, punctuation, and symbols are recognized as tag delimiters.
