Thanks I found that earlier while searching, but I am unsure with how to write the code.

You can start with this https://world.episerver.com/documentation/developer-guides/CMS/Content/icontentrepository-and-datafactory/

Even better, take a Developer course with Episerver training 

That's so unhelpful. Thank you.

epiNew,

Why is it unhelpful to suggest that you take developer training course?

TBH what Quan provided is the best that can be found around internet.

I would like to provide feedback to the community:

We solved it by adding a filter to the find function. The code included a seach carried out by Episerver Find which was pulling in content of a specific category. But instead of honoring the current language it was pulling in everything.

To fix it, we changed this:

search = search.Filter(sp => sp.IsDeleted.Match(false))
                .OrderByDescending(sp => sp.PublishingDate, SortMissing.Last)
                .Take(1000);

To this:

search = search.Filter(sp => sp.IsDeleted.Match(false))
                .OrderByDescending(sp => sp.PublishingDate, SortMissing.Last)
                .Filter(sp => sp.Language.Name.Match(ContentLanguage.PreferredCulture.Name))
                .Take(1000);

So now we are pulling only content that matches the preferred culture.

If you are searching for IContentData you should only have to apply the .FilterForVisitor() filter. It's doing all filtering necessary for current visitor, eg access rights, published content, current language.

search = search.FilterForVisitor()
               .OrderByDescending(sp => sp.PublishingDate, SortMissing.Last)
               .Take(1000);

Thanks for the tip, .FilterForVisitor() has exactly what's needed and would make the code far leaner.
