Performance and Incremental Crawling in WCM Search Open Mic Nov 13 2012 (edited).mp3.
|Q & A Transcript|
Q: Off-topic: Where can I find more info about using external search engines like Goggle Search Appliances working together with Portal? Looking for configuration docs.
A: This document might be helpful:
Q: Will these seed list issues apply when we use OmniFind to query Portal. We have seedlist in OmniFind to query Portal
A: Yes much so. The basic crawl mechanism or behavior does not change if the content is on Portal/WCM
Q: Is there anything between the relationship with the Portal search and the WCM authoring UI?
A: Prior to and including version 7 - Authoring UI search and the Portal search WCM content are independent. With Portal search. an indexer using the JCR search adds and removes the items from the repository. In version 8 there are changes to how they work in the background but are still independent, they do not use the same JCR indexer.
Q: WCM authoring search is not enabled by default. When in a cluster, does the WCM authoring search have to configured with Portal to index the WCM search? Ina cluster do you need to configure WCM search on a separate server for remote search as you do with Portal?
A: With remote WCM search rendering, you setup a remote search service and define WCM collections. For authoring, you have the JRC collections, you can make shared indexing. They are two deferent searches for authoring or rendering indexes. In the InfoCenter search for "remote JCR" or "remote authoring" and you should be able to find additional information.
