Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element modbo algorithm" » "element model 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 modbo algorithm") OR ("element method algorithms"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element modbo algorithm\") OR (\"element method algorithms\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element modbo algorithm ) OR ( element method algorithms ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element modbo algorithm") OR ("element method algorithms"))) OR ("data processing algorithm"))*.
