Westlaw has added a new feature called Smart Tools which offers suggestions for misspelled or incomplete searches.
According to Westlaw, “Smart Tools offer you alternatives for terms that appear out of context even though spelled correctly (statute of limitations for statue of limitations). They flag misspelled words and acronyms (HIPAA for HIPPA). And Smart Tools suggest related terms of art such as “frustration of purpose” for “impossibility of performance.” ”
