Perhaps you should try some spelling variations:
"tables logarithms" » "tables algorithms", "table algorithms", "large logarithms"
"all logarithms" » "math logarithms", "_ logarithms", "all algorithms"
"tree algorithm" » "true algorithm", "tree algorithms"

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 logarithms") OR ("tree algorithm"))) OR ("all logarithms")).
• Removing quotes may allow a broader search: (((( tables logarithms ) or ( tree algorithm ))) or ( all logarithms )).
• Adding a wildcard symbol may retrieve word variants: (((("tables logarithms") or ("tree algorithm"))) or ("all logarithms"))*.
