AEM Search Types

[AEM_Forum]

Hi all,

I am reading three types are Search in AEM: search-jcr, search-wcm, and searchenhanced.cq5wcm.

What are the differences among these three and when do we use what search?

Earlier, I read about QOM type as well.

Kindly suggest where I could get all these Search types listed along with their comparisons as well as code samples.

Appreciate your replies.

Thanks,

Rama.
