推荐答案

指定操作系统和打算执行的搜索类型(单词，精确短语，PDF元数据?)可能会有所帮助.某些内置搜索系统(例如OS X的Spotlight)会在您帐户中的所有PDF文件中自动搜索多个单词.

It may be helpful to specify your operating system and the types of searches that you intend to perform (words, exact phrases, PDF metadata?). Some built-in search systems like OS X's Spotlight will automatically search for multiple words across all PDF files in your account.

在Linux上，我可能会使用'pdftotext'实用工具将PDF文件临时转换为ASCII，然后使用'grep'搜索每个文件:

On Linux, I would probably temporarily convert PDF files to ASCII with 'pdftotext' utility and then search through each one with 'grep':

find /start/path -name '*.pdf' -print \
-exec pdftotext {} /tmp/tmp.txt \; \
-exec grep -i "search words" /tmp/tmp.txt \;
