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