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