Hi!

I can't understand the difference between ContentSearchHandler and IPageCriteriaQueryService. Their usage is quite similar, but with IPageCriteriaQueryService I can search in particular custom fields of page, while with ContentSearchHandler it seems impossible. But what is the real difference? When should I use ContentSearchHandler and when IPageCriteriaQueryService? What is the difference under hood?

There is no mentions of IPageCriteriaQueryService in Search documentation: https://world.episerver.com/documentation/Items/Developers-Guide/Episerver-CMS/9/Search/Search/

Also information about IPageCriteriaQueryService looks really poor: https://world.episerver.com/documentation/class-library/?documentId=cms/7/0ddfb696-31e8-03ca-b4b0-4f1644f04118

Hi,

FindPagesWithCriteria makes requests to database (https://world.episerver.com/documentation/Items/Developers-Guide/Episerver-CMS/9/Search/Searching-for-pages-based-on-page-type/).

ContentSearchHandler works with index (https://world.episerver.com/SdkDocuments/Developers-Guide/EPiServer-CMS/75/Search/SearchImplementOptions.PNG).
