Perhaps you should try some spelling variations:
matching algorithm » mining algorithm (Expand Search), sampling algorithm (Expand Search), tracking algorithm (Expand Search)
fluent processing » plant processing (Expand Search), light processing (Expand Search), text processing (Expand Search)
element matching » element mapping (Expand Search), employment matching (Expand Search), element modeling (Expand Search)
query processing » pre processing (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"element matching algorithm\\") OR (\\"((fluent processing) OR (query processing)) algorithm\\"))\"".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ( ((fluent processing) OR (query processing)) algorithm )).
