Lemons Search

A fast fuzzy finder and quick switcher with previews.

Lemons Search adds dedicated search views for files, aliases, commands, and note content. Each view includes keyboard navigation and a preview of the selected result.

The search engine runs in a background worker to keep the editor responsive.

Commands

• Lemons Search: Open search: Find files by path.
• Lemons Search: Open alias search: Find files by name or alias.
• Lemons Search: Open full-text search: Search Markdown note contents and preview the matching block.
• Lemons Search: Command palette: Find and run Obsidian commands.

Full-text search

Full-text search applies each query atom to individual words and requires all positive atoms to occur in the same Markdown block. Prefix an atom with ! to exclude blocks containing it.

By default, full-text atoms use fuzzy subsequence matching. For example, apl matches apple, but substitutions and transposed characters are not treated as general spelling corrections. The modifiers 'foo, ^foo, foo$, and ^foo$ request substring, prefix, postfix, and exact-word matching. Full-text matching is case-insensitive.

When Fuzzy search in full-text is disabled, plain atoms require exact words. Substring ('), prefix (^), and negation (!) remain available; postfix $ syntax is not supported in that mode.

Search syntax

Every query consists of search atoms separated by spaces. Escape a space with \ to keep it within one atom. In the following illustration, each underlined part is a separate search atom.

Modifiers change how an atom is matched:

• Substring: Prefix with '. For example, 'foo matches yummy food but not funny doodle.
• Prefix: Prefix with ^. For example, ^foo matches food but not yummy food.
• Postfix: Append $. For example, .md$ matches foo.md but not foo.txt.
• Exact: Combine ^ and $. For example, ^foo.md$ matches only foo.md.
• Negation: Prefix an atom with !, such as !foo, !^foo, or !.md$.

Lowercase atoms ignore casing. An uppercase letter makes file, alias, and command search case-sensitive. Full-text search remains case-insensitive.

Keyboard Navigation

While the input field is focused, use these shortcuts:

• ↑ Move selection up by one
• ↓ Move selection down by one
• Home Move selection to the first item
• End Move selection to the last item
• Enter Open selection in same tab
• Ctrl + Enter Open selection in a new tab
• Tab Copy the current selection into the search bar
• Escape Cancel the search

Some shortcuts can be changed in the plugin settings.

Mouse Navigation

• Click a suggestion to open it in the same tab.
