Was that the Acrobat search tool, or browser's?
I use the Firefox browser, and when I first click on one of these filings on OTCMarkets, it opens in a frame on the page, but not all the file may actually load for search purposes. I then right click on the filing itself and Save what's in the frame to a PDF in my "MJNA Disclosures" folder.
Then I open with Acrobat and use that program's search function.
In IE, once you've got the report open, try the "Download Report" button above the frame, and if the Acrobat add-on is installed, it should reopen with the Acrobat interface.
Or perhaps you just misspelled "Llamas" :-)
