The document discusses two types of search helps in ABAP: elementary and collective. Elementary search helps define a basic search path and where to retrieve data, while collective search helps combine multiple elementary search helps to provide alternative search options to the user. Search helps can be statically or dynamically attached to selection screen fields or dynpro elements.
