Installing ADF WebUI: If SearchIndexerEngineName=OracleTextSearch was already set in General Config

Good Day,

I am currently Installing the Webcenter Content 11.1.1.8.0 Content UI in test environments following to the instructions in this guide (Doc ID 1618305.1) and Step 7 says to rebuild the Content Server Index.

Step 7) Make sure that Content Server index is rebuilt using OracleTextSearch.

Using the native webUI, Administration --> Admin Applets --> Repository Manager

Select the Indexer tab.

Under the "Collection Rebuild Cycle", click the Start button

Uncheck Use Fast Rebuild box

Click the OK button.

Prior to this Step 5 in the guide says to set the following in Configuration Variables if not already set:

SearchIndexerEngineName=ORACLETEXTSEARCH

I already had that setting in place before I upgraded to 11.1.1.8 so my question is do I still need to do a full collection rebuild? Its not a problem for our test environments because they don't have a lot of content but that's not the case for Production.
