Google Drive handled this test with relative ease, uploading and recognizing text in 174 political candidate disclosure forms in about 40 minutes.
The Google service performed well, but not perfectly, in our tests for accuracy, which involved searching the forms for the candidates' stock holdings. It correctly found the two with holdings in "Pfizer." It found three of five with IBM stock, and five of six with stock in BB&T, though that search required the user to enter different variants of the stock symbol.
Drive and Docs missed two of the candidates because they entered their info in addendum tables, which the OCR feature failed to capture. In the third miss, the information came on page 14, and Google's documentation notes that its OCR stops recognizing text after 10 pages.
Docs' OCR function also will not accept any file larger than 2MB; in this test, the files ranged from 151KB to 768KB.
