Content Type
By default a search is carried out on both metadata and content.
The metadata is the structural information which helps us describe the contents of the whole of the web site. Examples of metadata are Tables of Contents, Table Titles, Page Titles, etc. The content is made up of the words in the original texts. Searching by metadata only will always return fewer results than searching both content and metadata, but the results will be returned more quickly and may provide a more precise defined result.
