Lexis: Natural Language Searches |
 |
L3 |
 |
| However,
you were expecting to find more cases on the subject. There is a
journal article on the topic that cites 15 of such cases, and you are confident
that there are many other "uncited" cases as well. You decide to
reformulate the search as a natural language search.
First, you simply type in the research question: Can a profit sharing plan serve a dual purpose as a health or accident plan under IRC 105?Since natural language searches use term weighting, you decide to give more weight to certain terms by repeating them a second time. In this case you repeat the terms: dual purpose health accident plan. The result will be that documents with a heavy presence of these terms will be bumped up to the top of the list. Since documents are not required to have every term listed in a natural language search (they score higher if they do, however), you could also make certain terms mandatory by clicking the "Restrict Search Using Mandatory Terms" link. |
