Solr Indexing and Searching using same instance
===

While doing Incremental Indexing in Solr using the same Solr instance used for searching, can the two (incremental update and search) happen simultaneously without affecting normal search. I mean I dont want the new records to be searchable right at that moment but my normal search should not have problems while incremental indexing is going on. If yes, then will the commit operation automatically done for all the new documents added in Solr index automatically after some time? Also in this case will there be two or more segments after each incremental crawl or will there be only one segment (records would be merged)?
