Introduction:

This article provides some standard questions and answers concerning re-indexing documents in Vault.

Q&A:

1. What is the approximate time required to perform a full re-index of all documents in Vault?
   
   A full reindex in Vault should take approximately 90 minutes. This can vary quite a bit based on how busy the POD is, but 90 minutes is a good estimate. It may take less time than that. We recommend reindexing at the end of the day when there are fewer people logged into Vault so it proceeds faster.
   
   
2. Will performing a full re-index on documents have any other potential impact, e.g. impact on reports, interfaces?
   
   A full reindex corrects any data in the index that is out of sync with the database. So, it is possible that the output of a report is slightly different or that search results may change. Those corrections in the index can result in a document matching the criteria of a report that did not match before. 
   
   
3. Will re-indexing the affected documents do the following:
   
   a. Change the last modified date on any documents?
   
   Reindexing does not change any of the data including the last modified date. This index is a searchable copy of the database and the database is the source of truth. In this case, some updates are not properly copied to the index. This happens every once in a while when the search engine has an error.
   
   b. Change anything about the viewable renditions on any documents?
   
   There is no impact to the viewable renditions. Indexing is a searchable version of the text data and is a separate system from the viewable renditions.
