Perhaps you should try some spelling variations:
multilayered reservoirs » multilayer reservoir, multilayered reflectors
multilayered reservoir » multilayered research
multipole reservoir » multiple reservoir, multiple reservoirs, multipurpose reservoir
multiple receptors » multiple receivers, multiple exceptions, multiple factors
multiple receptor » multiple receivers, muscle receptor, multiple record

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((((multipole reservoir) OR (multiple receptor))) OR (multiple receptors))) OR (multilayered reservoirs))) OR (multilayered reservoir)).
• Adding a wildcard symbol may retrieve word variants: ((((((((multipole reservoir) or (multiple receptor))) or (multiple receptors))) or (multilayered reservoirs))) or (multilayered reservoir))*.
