About searching Adobe PDF documents
Acrobat provides several ways for you to find what you're looking for.
You can search within PDF documents to find a word fragment, word, or phrase. You can
search the text, comments, bookmarks, and document information (metadata).You can
search from within Adobe Reader or your web browser. You can search one file or
multiple files, and you can even search PDF documents without opening them.
To search solely in the document that you have open, use the Find command. You can
limit your search by matching only whole words or making the search case-sensitive, or
you can extend the search by searching bookmarks and comments as well as text. (See
About searching text.)
To extend the search to documents other than the one you have open or to access more
advanced search features, including the use of Boolean operators such as AND, OR, and
NOT to further refine your search, use the Search command. (See Searching across
multiple Adobe PDF documents and Using Boolean queries in multiple-document
searches.)
If you have the full version of Adobe Reader and if the collection of documents that you
are searching has been indexed using Acrobat Catalog, you can search the index for a
word rather than searching each document. A full-text index search is much faster than
searching all the text in the documents.

English languages in Adobe PDF files.
