Global searcher

[francostan]

Hi there :)

This pull request creates the search functionality by reading file contents on-demand during search operations, rather than loading all file contents into memory upfront. This approach maintains low memory usage while ensuring accurate search results across entire file contents.​

Changes Implemented:​

• Create the Input for the search on the Sidebar.

• Create filteredEntries to read file contents dynamically during search.

• Ensured that the search is case-insensitive and trims whitespace from the search query.

Example:

I really like using this app, thanks by the way
