Connector Order and Priority
Lexis® uses the following order of operations for connector searches:
- ( ) have the highest priority. If parentheses are present in a search, things enclosed in parentheses are dealt with first.
- proximity connectors1, such as near/n, onear/n, /seg, w/n, pre/n, NOT/n, NOT/seg, /s, /p, w/sent, w/para
- not / and not
Example: bankrupt! w/25 discharg! and not student or college or education! w/5 (loan and scholarship)
This search query is processed in the following way:
- ( ) has the highest priority, so the terms and connectors within the parentheses operate first. In this example, (loan and scholarship) are processed as a unit before any other connectors apply.
- or has the next highest priority, so it operates next. In this example, student or college or education! is processed as a unit, which is created by the or connector.
- w/5 ties together the term loan and the student or college or education! unit.
- w/25 operates next and creates a unit of the bankrupt! w/25 discharg! terms.
- and not, with the lowest priority, operates last and links the units formed in the second and third items above.
1 Proximity connectors are processed from the smallest to the largest. This is also the case if you use the same connector more than once in your search string.
