Perhaps you should try some spelling variations:
"flow distribution" » "flaw distribution", "fhow distribution", "fflow distributions"
"low distribution" » "law distribution", "how distribution", "flow distributions"
"bzw distribution" » "new distribution", "law distribution", "how distribution"

Try widening your search to All Fields.

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: (((("flow distribution") OR ("low distribution"))) OR ("bzw distribution")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"flow distribution\") OR (\"low distribution\"))) or (\"bzw distribution\"))".
• Removing quotes may allow a broader search: (((( flow distribution ) OR ( low distribution ))) or ( bzw distribution )).
• Adding a wildcard symbol may retrieve word variants: (((("flow distribution") OR ("low distribution"))) or ("bzw distribution"))*.
