Perhaps you should try some spelling variations:
"parts logarithms" » "roots logarithms", "large logarithms", "matrix logarithms"
"math logarithms" » "matrix logarithms", "smooth logarithms", "math algorithms"
"all logarithms" » "_ logarithms", "all algorithms", "10 logarithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("all logarithms") OR ((("math logarithms") OR ("parts logarithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"all logarithms\") or (((\"math logarithms\") OR (\"parts logarithms\"))))".
• Removing quotes may allow a broader search: (( all logarithms ) or ((( math logarithms ) OR ( parts logarithms )))).
• Adding a wildcard symbol may retrieve word variants: (("all logarithms") or ((("math logarithms") OR ("parts logarithms"))))*.
