How it works in a data room
When files arrive, the platform extracts their text and builds a search index. Typed PDFs, Word files and spreadsheets are read directly, while scans go through optical character recognition first so their words become searchable too. A reviewer types a phrase such as “change of control” and gets a list of documents with highlighted hits, filtered by folder, file type or date. Results respect permissions, so a user never sees a snippet from a folder hidden from their group. Stronger tools support exact phrases, Boolean operators and searches in several languages.
Why it matters in a deal
Due diligence runs on deadlines. A buyer’s lawyers may need to find every contract with an exclusivity clause across hundreds of agreements, or every mention of a pending dispute in board minutes. Without search inside the text, they would open files one by one. Fast search also helps the seller answer questions quickly, and it is a practical test when you compare providers: load a few scanned files during a trial and check whether the search finds words within them.
Example
An investment firm reviewing a hospital group in India needs to confirm which supplier contracts allow termination on a change of ownership. Its associate searches “assignment” and “change of control” across the commercial folder and finds 38 matching agreements in under a minute, including a dozen scanned originals from the early 2010s. The team tags those for the lawyers and moves on, instead of spending two days reading every page.
