Quick Sidebar Switching and Global Search

💡 The sidebar is a handy drawer for quickly swapping document files between study sets. It serves mainly as a file box, and when needed it lets you quickly switch to other projects and search global information, making it easy to cross-reference multiple materials.

3 Appendix: Full-text Search Supports Some Advanced Rules

The keywords AND, OR, NOT, and NEAR can be used to combine conditions and must be uppercase. (Lowercase versions are treated as ordinary search terms.) Examples: word1 AND word2 (contains word1 and word2) word1 OR word2 (contains word1 or word2) word1 NOT word2 (contains word1 but not word2) word1 NEAR word2 (contains word1 and word2, with the two words close together) word1 NEAR/2 word2 (contains word1 and word2, with the two words close together; the number indicates the proximity—the smaller it is, the closer they must be) You can use parentheses to combine the above conditions into complex matching logic, for example: word1 OR (word2 NOT word3)

A lowercase search term uses the beginswith matching mode. An uppercase search term uses the fullmatch matching mode.

When searching document content, you can use file: to limit which files are searched, for example: word1 file:Name2 (searches for the keyword word1 in the text content of PDFs whose directory/file name contains Name2.
