Have you ever remembered that there is some important information in one of your pdf documents, but you don’t remember which of those documents contains the information? Perhaps a sinking feeling of dread came upon you, as the prospect of going through the documents one by one and searching pushed aside happy emotions in you? Wouldn’t it be nice to be able to search through all those hundreds of documents with one click, or one command-line command? (like using something like “grep” to search multiple text files at once)

Guess what? Adobe Acrobat provides that capability!

Just select “Advanced search” under the “Edit” main menu. Nice.
