Search within files in search result in Sublime - sublimetext2

Question

I often use Sublime Text 2's search all open files/folders feature (CMD+SHIFT+F).
Is it possible to perform a second search that only queries files which contain the first search query?
For example: Search 1 finds 5 files that contain "hello". Search 2 should only query those same 5 files for "world", so the resulting matches will be files which contain both "hello" and "world".
I can search the text which is visible in the results buffer (such as in the screenshot below), but I'd like to search the entire contents of all files that are shown in the results buffer.

1:
Open the find_in_files panel with Ctrl + Shift + F.
In the example, <open folders> is used for the Where: argument, but you can use whatever fits your initial search criteria.
2:
Open the find panel with Ctrl + F while you are still in the results buffer.
Enter ^(/Users/.*)(?=:$) as your Find: argument, and make sure the RegEx switch is enabled. This RegEx pattern will match all of the paths within the results.
( Windows users can enter ^(C:\\.*)(?=:$) )
Copy the selected paths.
3:
Paste the copied paths into a blank document.
Open the replace panel with Ctrl + H.
Enter ^(/Users/.*)(\n) as the Find What: argument, and $1$2,  as the Replace With: argument. This will effectively convert all of the lines into a single line of comma separated values.
( Windows users can enter ^(C:\\.*)(\n) )
Copy the resulting line.
4:
Open the find_in_files panel with Ctrl + Shift + F.
Paste the copied path list as your Where: argument, and enter your second query as the Find: argument.
5:
Repeat as necessary.
