Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"text using algorithms" » "text pacing algorithms" (Expand Search), "text nine algorithms" (Expand Search), "text sorting algorithms" (Expand Search), "test using algorithms" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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: (((("text using algorithms") OR ("image processing algorithm"))) OR ("element cscap algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"text using algorithms\") OR (\"image processing algorithm\"))) OR (\"element cscap algorithm\"))".
• Removing quotes may allow a broader search: (((( text using algorithms ) OR ( image processing algorithm ))) OR ( element cscap algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("text using algorithms") OR ("image processing algorithm"))) OR ("element cscap algorithm"))*.
