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)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element g 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 ("element te algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithms\") OR (\"element te algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element data algorithms ) OR ( element te algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element data algorithms") OR ("element te algorithm"))) OR ("query processing algorithm"))*.
