Searching Across Multiple Files

A single document is easy to search once you have opened it. Multi-file search in the Keyline app lets you ask a question across every document in your library at once, so you do not have to open each file individually to find what you need. Through the Keyline API this is the default: a call searches the whole project rather than one file.

Searching across your library

Start a search from your library instead of from a single document. Keyline searches every processed file at once and returns the passages, figures, and tables most relevant to your question, each with a citation back to its source document and page.

How the multi-file index works

Every file you upload is added to a shared search index as part of processing. This index is what makes cross-file search fast: instead of re-reading every document at search time, Keyline searches the index and then confirms the most relevant matches directly against the source pages.

Grouping results into bundles

When a search turns up a useful set of files, you can group them into a bundle so you can come back to that same set later without searching again. See Organizing your library for more on bundles.
