Perhaps you should try some spelling variations:
formation process » formation processes, creation process, fermentation process
using decision » business decision, making decisions
process using » processes using, processing using
data creating » data cleaning
data testing » data fitting, a testing, data writing
data peng » data pet, data penting

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

• Performing a fuzzy search may retrieve terms with similar spellings: formation process using decision ((data peng) or (((data testing) or (data creating))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: formation process using decision ((data peng) OR (((data testing) OR (data creating)))).
• Adding a wildcard symbol may retrieve word variants: formation process using decision ((data peng) or (((data testing) or (data creating))))*.
