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)
"image 1_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_single algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas 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: (((("image 1_using algorithm") OR ("data processing algorithm"))) OR ("settlement data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"data processing algorithm\"))) OR (\"settlement data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( data processing algorithm ))) OR ( settlement data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("data processing algorithm"))) OR ("settlement data algorithm"))*.
