推荐答案
按扫描我假设你的意思是使用OCR提取文本？
By "scan" I assume you mean use OCR to extract text?
在谷歌驱动器的OCR功能是pretty的限制。
The OCR feature on Google Drive is pretty limited.

它会扫描图像或PDF文件高达2MB的大小，这并不多。文本扫描在中等分辨率和存储为JPG格式的单页，有时会不止于此。降低分辨率将允许多个页面，同时也使OCR结果不可靠。如果你想存储多页的PDF扫描或TIFF格式，你会倒霉。
It will scan images or PDFs upto 2MB in size, which isn't much. A single page of text scanned at moderate resolution and stored as JPG format will sometimes be more than that. Reducing the resolution will allow more than one page, but also make the OCR results less reliable. If you want to store multi-page PDF scans or TIFFs you'll be out of luck.
我测试了单页扫描从保险单据，并做了工作，对文件中的话，我可以（几分钟后）搜索。
I tested a single scanned page from an insurance document and it did work, I could (after a few minutes) search on words in the document.
我想你会更好地考虑存储在谷歌驱动器的图像，pre-处理有独立的OCR库后。
I think you would be better to consider storing the images on Google Drive, after pre-processing with a separate OCR library.
