About Samurai Search
Search source code, plain text files and PDF files on your iOS device or in iCloud/USB/SMB, then open matched files in your favourite editing/viewing app.
Supports flexible search options, including regular expressions (for plain text files). Files searched can be selected from standard or custom text file types.
Search folders can be selected from On My iPad, iCloud Drive or external file providers (e.g SMB/USB folder). Saved search folders are retained by the app where possible.
Note some third party file providers don’t currently provide external folder access (eg Google Drive and Dropbox).
If an iCloud Drive folder is selected, the Download iCloud Files option will appear.
This option, when enabled, will download iCloud files in selected iCloud Drive folders that match the file type (file extension) criteria, if they are known, yet not downloaded on the device.
Typically this needs to be only run once before a set of search queries. For this reason the option resets after use. It is re-enabled if the file type criteria are changed. It can also be enabled manually.
