In order to plan the Incremental and Full Crawl scenarios and schedule , I’m adding the below information in this regard:
Note1: a full crawl should be done at least once before performing incremental crawl.
Note2: the above scenarios are covered for crawled content within SharePoint 2010/2013 farm, (not file shares , exchange public folders, custom connectors , etc… for those scenarios incremental crawl behavior might differ).
How about .SystemUpdate()? It seems like that one is only picked up by Full Crawl.
It seems that (at least in 2010) security changes are taken into account on incremental fileshare crawl!
Thanks Issa for putting this together - very helpful. You readers might be benefited from this related post too:
SharePoint 2010 is NOT finding searchable text within certain PDF documents. I have changed the Attribute properties and uploaded the file again. It still does not work, but I'm not sure a full crawl has been done. Should that fix the problem?
Chris... Are you finding content in any pdf documents? Also, are you sure the text is searchable? If you open the document in Adobe Acrobat Reader, you should be able to select the text using your mouse if it is searchable.
Nice post and so informative.. what if the files are moved from one folder to another folder with in the same document library.. do we need full crawl or incremental ?
