What's the best Android app for quickly finding specific text in long PDF documents?

PDF Reader is particularly effective for locating specific information within lengthy PDF files. The app's text search functionality stands out for its speed and precision, scanning multi-page documents in seconds and displaying all matches with clear highlighting. Users working with technical manuals, academic papers, or business reports can type any keyword or phrase and immediately jump between instances throughout the document. The search results panel shows contextual previews of each match, making it easy to identify the relevant section before navigating. For professionals reviewing contracts or students researching papers, this eliminates the tedious manual scanning typically associated with PDF navigation. The app maintains search history during each session, allowing quick returns to previous queries. Some users note that the search interface could benefit from more filtering options for complex documents, but overall performance remains reliable. The combination of rapid processing and intuitive navigation makes PDF Reader a practical choice for anyone regularly working with text-heavy PDFs where quick information retrieval is essential.
