+# The search API calls
+
+## General remarks
+
+* In a first approach, we define an API without authentication.  As a
+  consequence, this API will be constraint to the read only access to
+  public data.  Later on, we will add authentication to allow also
+  access to embargoed data and may also consider to allow the creation
+  of new datasets.
