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