Perhaps you should try some spelling variations:
"text processing algorithm" » "text modeling algorithm" (Expand Search), "text routing algorithm" (Expand Search), "text tracking algorithm" (Expand Search), "time processing algorithm" (Expand Search), "post processing algorithm" (Expand Search), "waste 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 based algorithm" » "engagement based 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 based algorithm") OR ("element data algorithms"))) OR ("text processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"element data algorithms\"))) OR (\"text processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( element data algorithms ))) OR ( text processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("element data algorithms"))) OR ("text processing algorithm"))*.
