Some connectors perform incremental crawls based on snapshot entries, which are meant to match the exact documents that have been indexed by the connector to the search engine. On an incremental crawl, the connector fully crawls the repository the same way as a full crawl, but it only indexes the modified, new or deleted documents during that crawl.
For a discussion on crawling, see Full & Incremental Crawls.
Failing to save a content source before creating or editing another content source can result in an error.
ERROR [aspire]: Exception received attempting to get execute component command com.searchtechnologies.aspire.services.AspireException: Unable to find content source
Save the initial content source before creating or working on another.
After a crawl has finished, the connector status may not be updated correctly.
To confirm this, do the following:
1. In RoboMongo, go to your connector database (like: aspire-nameOfYourConnector).
2. Open the "Status" collection and perform the following query:
db.getCollection('status').find({}).limit(1).sort({$natural:-1})
3, Edit the entry and set the status to "S" (Completed).
Note: To see the full options of "status" values, see MongoDB Collection Status.
