Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (Expand Search)
"client needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "urgent needs algorithm" (Expand Search), "china needs 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: (((("element data algorithms") OR ("query processing algorithm"))) OR ("client needs algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithms\") OR (\"query processing algorithm\"))) OR (\"client needs algorithm\"))".
• Removing quotes may allow a broader search: (((( element data algorithms ) OR ( query processing algorithm ))) OR ( client needs algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element data algorithms") OR ("query processing algorithm"))) OR ("client needs algorithm"))*.
