In order to use both indexes, you could exclude the NewsView Control from the PageIndex, so that all news results will come from the News Index, not from the NewsView control of the Page Index.
You can do this by excluding the content place holder, where the NewsView Control is placed,from the PageIndex:
1. Open the ~\App_Data\Search\YourSearchIndexName\fieldsInfoProvider.xml
2. Add the following line:
|<field name="JustTypeSomeName" weight="-1" indexAttribute="" filterTag="div" filterAttributes="id:TypeIDofThePlaceHolderHere" />
Have in mind that you need to add such a line for each NewsView control and put its content placeholder ID in the filterAttribute
Hope this helps.
