Find index has a lot of objects of type GenericMedia. How can I reduce them?
Add an initialization module and add: ContentIndexer.Instance.Conventions .ForInstancesOf<GenericMedia>() .ShouldIndex(x => false);
For more information, check out the indexing documentation.
Greate, shall check now. By the way, how can I delete the duplicate results, and sometimes even not used(not linked) from Find index?
There should not be duplicated results if you've done standard indexing. I suggest your re-run the Find indexing job.
You could use the ShouldIndex method to modify which content that should be indexed or not.
