Perhaps you should try some spelling variations:
"bounded theories" » "grounded theories", "bounded queries", "grounded theorie"
"bounded theory" » "blended theory", "bounds theory", "grounded theory6"
"founded theory" » "grounded theory6", "founding theory", "coupled theory"
"grounded theory" » "ground theory"

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: (((("grounded theory") OR ((("bounded theory") OR ("bounded theories"))))) OR ("founded theory"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"grounded theory\") or (((\"bounded theory\") OR (\"bounded theories\"))))) or (\"founded theory\"))*".
• Removing quotes may allow a broader search: (((( grounded theory ) or ((( bounded theory ) OR ( bounded theories ))))) or ( founded theory ))*.
