Example of combining connectors and proximity searches

When combined, connectors and proximity searches can be an important element in performing narrowly defined yet comprehensive searches.
Example: ("partner deduct*" /p "excise tax") not "income tax"
Finds: documents containing the phrase partner deduction or partner deductible and the phrase excise tax or excise taxes within a paragraph (or 50 words of each other), but not if the phrase income tax appears in the document.
