AFAIK CQ segments are always evaluated on the client side to maximize the efficiency of the Dispatcher/Akamai caches.  You have to implement own method for server side.

it all deponds on your structure & number of nodes.  respectDocumentOrder will surely be expensive compared to node.getNodes()

Usually you don't have a search when you want the node order and can simply use navigational access (node.getNodes()) in that case. Example at [1] and then in logic you can apply filter.   In Jackrabbit/CRX you can globally configure "respectDocumentOrder" for the query index, which is turned off by...

Your requirement does not look like sorting. It is about filtering. You can meet it using [1] & might be additional filtering. [1]   http://dev.day.com/docs/en/cq/current/developing/customize_siteadmin.html

AFAIK the dictionaries used by spellcheck are loaded once and cached in memory. There is no mechanism to clear this out if the user add new entries to the dictionary.Restart the instance to get the new entry added & verify

Look at Geometrixx-Outdoors product ones which trigeers onLoad. Use the HTML attribute "record" to send the data during initial document load.More details at http://dev.day.com/docs/en/cq/current/developing/extending-cq-analytics.html#Tracking%20Custom%20Events%20On%20Page%20Load

I have requested author of blog to respond. Also you can request additional information in that same blog post. Meantime do you see any error in the console?

The OSGi spec allows it & Our JCR Installer and the Web Console  don't support this as we discourage deploying multiple version of same bundle. Hence it is not possible OOB

Off cource you can. In 5.3 there was an issue but should work with latest version.
