-## How to customize document type in the Software Catalog index
-
-In some cases you might want to have the ability to change the document type in which catalog entities will be indexed by catalog collator.
-Such option gives a possibility to customize SearchPage results and filters depending on which document type you would like to see results for.
-
-You can achieve that by passing additional parameter `documentType` to the `DefaultCatalogCollatorFactory`.
-
-Let's say that you want to have two different document types for some entities.
-Our example will cover a use case in which we want to:
-
-- Store entities of kind `User` or `Group` under document type `yourCustomDocumentType`,
-- Store rest of entities under default document type `software-catalog`
-
-To achieve that you will have to remove `User` and `Group` from your previous collator `filter` and register new `DefaultCatalogCollatorFactory` with new parameter `documentType`.
