Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"image 1_using algorithm" » "image cosine algorithm" (Expand Search)
"element ree algorithms" » "element deer algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element rd algorithm" (Expand Search), "elementi per algorithms" (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: (((("data processing algorithm") OR ("image 1_using algorithm"))) OR ("element ree algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"image 1_using algorithm\"))) OR (\"element ree algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( image 1_using algorithm ))) OR ( element ree algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("image 1_using algorithm"))) OR ("element ree algorithms"))*.
