Perhaps you should try some spelling variations:
implementation semantic » implementation semantics, implementing semantic, representation semantic
documentation semantic » argumentation semantics, fragmentation semantic, documentation center
precision data » decision data, precision dairy, precision a
data lieven » data level, data sieving

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "communication ((documentation semantic) OR (implementation semantic)) precision data lieven~".
• Adding a wildcard symbol may retrieve word variants: communication ((documentation semantic) OR (implementation semantic)) precision data lieven*.
