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