+|Size of document that can be downloaded by the crawl components  |All File Types: 150 MB <br/> PDF, PPTX, PPT, DOC, DOCX: 512 MB |Boundary  | Crawl processing supports files up to 150 MB for all types, with an extended limit of 512 MB for PDF, PPTX, PPT, DOC, and DOCX formats. For files exceeding these limits, only document metadata is downloaded, while the full content is NOT downloaded and remains unavailable for search.  |
 |Parsed content size  |2 million characters  |Boundary  |Search stops parsing an item after it has parsed up to 2 million characters of content from it, including the item's attachments. The actual number of parsed characters can be lower than this limit because search uses a maximum of 30 seconds on parsing a single item and its attachments. When search stops parsing an item, the item is marked as partially processed. Any unparsed content isn't processed and therefore isn't indexed.  |
 |Characters processed by the word breaker  |1,000,000  |Boundary  |Search breaks content into individual words (tokens). The word breaker produces tokens from the first 1,000,000 characters of a single item, including the item's attachments.  <br/> The actual amount of tokens can be lower than this limit because search uses a maximum of 30 seconds on word breaking. Any remaining content isn't processed.  |
