Perhaps you should try some spelling variations:
"participation beginning" » "participation building", "participation giving", "participation planning"
"participation targeting" » "participation budgeting", "participation targets", "participation acting"
"participation learning" » "participatory learning", "participation planning", "participation acting"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("participation beginning") OR ("participation learning"))) or ("participation targeting"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("participation beginning") OR ("participation learning"))) OR ("participation targeting")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"participation beginning\") OR (\"participation learning\"))) or (\"participation targeting\"))".
• Removing quotes may allow a broader search: (((( participation beginning ) OR ( participation learning ))) or ( participation targeting )).
• Adding a wildcard symbol may retrieve word variants: (((("participation beginning") OR ("participation learning"))) or ("participation targeting"))*.
