אולי כדאי לנסות איות אחר או כתיב מלא:
conservation documentation » observation documentation, information documentation, conservation foundation
creating documentation » generating documentation, teaching documentation, processing documentation
using precise » using piecewise, using precision, using price
precise data » imprecise data, promise data, recipe data
data base » data bases

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: ((creating documentation) OR (conservation documentation)) using precise data base~.
• Adding a wildcard symbol may retrieve word variants: ((creating documentation) or (conservation documentation)) using precise data base*.
