Summary | This post shows how to delete a crawled property and how to prepare it.Deleting a crawled property might be necessary if
- you are developing a custom indexing connector and are still testing it; obsolete properties will accumulate over time
- your BDC changes from time to time and every change leads to new crawled properties being created with the next full crawl
Deleting unused crawled propertiesIn SharePoint 2010 deleting a single crawled property is not possible. But you can delete all unused crawled properties of a category.
Go to Metadata Properties and click Categories:
Unmapping and unindexing
You have to remove all mappings from the property and you also have to remove it from the search index.
Click Edit/Map Property in the context menu of a crawled property:
- remove all mappings for this property
- do not include values for this property in the search index
Note: Some OOB SharePoint crawled properties cannot be deleted.
