Explanation:
Farm has 1 Search Service Application configured
MrDonivan (US, 30.06.13):
Dump states to create a dedicated SQL instance. I believe this is wrong. as it will not resolve the issue that the current Search Service App is already at its hard boundary of 5 content databases. Limit of 5 is detailed here: (http://technet.microsoft.com/en-us/library/cc262787.aspx#ContentDB) This one item then also eliminates other options of "set MaxCrawlDatabase parameter to 6" and "add crawl database to contains the litware knowledgebase content" Only option that remains is:
Provision a new SearchServiceApplicaiton and configure it to crawl the Litware KB content.
Themaximum number of crawl databases is 5 per Search service application so we need another Search service application.
This maximum limit is increased to 15 with an Office 2013 update but the question doesn't mention that this update is installed so we haveto assume the question was written before the update was released.

Recommended value for crawl databases is 5 per search service application.
