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