### Crawling
|
|
|
|
Ambar 2.0 only supports local fs crawling, if you need to crawl an SMB share of an FTP location - just mount it using standard linux tools.
|
|
Crawling is automatic, no schedule is needed since the crawler monitors fs events and automatically processes new files.

## FAQ
|
|
### Is it open-source?
|
|
Yes, it's fully open-source.
|
|
|
|
### Is it free?
|
|
Yes, it is forever free and open-source.
|
|
|
|
### Does it perform OCR?
|
|
Yes, it performs OCR on images (jpg, tiff, bmp, etc) and PDF's. OCR is perfomed by well-known open-source library Tesseract. We tuned it to achieve best perfomance and quality on scanned documents. You can easily find all files on which OCR was perfomed with `tags:ocr` query
|
|
|
|
### Which languages are supported for OCR?
|
|
Supported languages: Eng, Rus, Ita, Deu, Fra, Spa, Pl, Nld.
|
|
If you miss your language please contact us on hello@ambar.cloud.
|
|
|
|
### Does it support tagging?
|
|
Yes!
|
|
|
|
### What about searching in PDF?
|
|
Yes, it can search through any PDF, even badly encoded or with scans inside. We did our best to make search over any kind of pdf document smooth.
|
|
|
|
### What is the maximum file size it can handle?
|
|
It's limited by amount of RAM on your machine, typically it's 500MB. It's an awesome result, as typical document managment systems offer 30MB maximum file size to be processed.
