Perhaps you should try some spelling variations:
"tables algorithms" » "tableau algorithms", "trees algorithms", "tableau algorithm"
"all logarithms" » "math logarithms", "all algorithms", "10 logarithms"
"_ logarithms" » "_ logarithmic"

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: (("tables algorithms") OR ((("all logarithms") OR ("_ logarithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tables algorithms\") or (((\"all logarithms\") OR (\"_ logarithms\"))))".
• Removing quotes may allow a broader search: (( tables algorithms ) or ((( all logarithms ) OR ( _ logarithms )))).
• Adding a wildcard symbol may retrieve word variants: (("tables algorithms") or ((("all logarithms") OR ("_ logarithms"))))*.
