Perhaps you should try some spelling variations:
"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)
"image 3_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 4_using algorithm" (Expand Search), "image 3_single algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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 ("image 3_using algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image 1_using algorithm\") OR (\"image 3_using algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( image 1_using algorithm ) OR ( image 3_using algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image 1_using algorithm") OR ("image 3_using algorithm"))) OR ("element data algorithm"))*.
