Is there any way to search for phrase in multiple pdfs simultaneously

Is there any way to search for phrase in multiple pdfs simultaneously? For example I have openned 4 pdfs and I look for phrase: "cat" in all of them at the same time?

One way of many possible would be to use PDF-XChange Viewer

• it can search in all open .PDFs or any selected folder
• can search for phrases or whole words

I assume you mean with "at the same time" that you want a one-click solution

You can use Adobe Reader to find text in multiple PDFs:

The Search window enables you to look for search terms in multiple PDFs. For example, you can search across all PDFs in a specific location or all files in an open PDF Portfolio.

1. Open Acrobat on your desktop (not in a web browser).
2. Do one of the following.
   • In the Find toolbar, type the search text, and then choose Open Full Acrobat Search from the pop-up menu.
   • In the Search window, type the search text.
   • Shift + Ctrl + F
3. In the Search window, select All PDF Documents In. From the pop-up menu directly below this option, choose Browse For Location.
4. Select the location, either on your computer or on a network, and click OK.
5. To specify additional search criteria, click Show Advanced Options, and specify the options.
6. Click Search.

Note: If documents are encrypted (have security applied to them), you cannot search them as part of a multiple-document search. Open those documents first and search them one at a time. However, documents encrypted as Adobe Digital Editions are an exception and can be searched as part of a multiple-document search.

During a search, you can click a result or use keyboard shortcuts to navigate the results without interrupting the search. Clicking the Stop button under the search-progress bar cancels further searching and limits the results to the occurrences already found. It doesn’t close the Search window or delete the Results list. To see more results, run a new search.
