Perhaps you should try some spelling variations:
"data processing algorithm" » "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "data boosting algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element four algorithms" » "element group algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element ore 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: (((("data processing algorithm") OR ("data modeling algorithm"))) OR ("element four algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"data modeling algorithm\"))) OR (\"element four algorithms\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( data modeling algorithm ))) OR ( element four algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("data modeling algorithm"))) OR ("element four algorithms"))*.
