Perhaps you should try some spelling variations:
"post routing algorithm" » "post modeling algorithm" (Expand Search), "post finding algorithm" (Expand Search), "post making algorithm" (Expand Search), "post docking algorithm" (Expand Search), "post dosing algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data fusion algorithm" (Expand Search), "data making algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("relevant data algorithm") OR ((("data using algorithm") OR ("post routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"data using algorithm\") OR (\"post routing algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( data using algorithm ) OR ( post routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("data using algorithm") OR ("post routing algorithm"))))*.
