用關鍵字搜索在 PDF 中定位資訊

Search in a PDF viewer allows users to quickly locate specific words, phrases, or data within a document without manually scanning each page. By instantly highlighting and navigating between results, search makes it easier to work with large or complex PDFs such as reports, manuals, contracts, or research papers. This functionality improves productivity by helping users find relevant information faster, understand content in context, and move directly to important sections.
