Proximity Operators

Allow searchers to specify that search terms be near others within a certain number.

The NEAR operator may allow for two words to be a certain distance apart.   Sometimes you can specify the maximum distance, or specify whether the words need to be in a specific order, or if either word can come first.

Example: "global warming" NEAR icebergs   would find records that contain both words no further than ten words apart depending on the search tool.

The BEFORE operator is similar to NEAR.  The first term before this operator has to occur within a specified word distance BEFORE the term on the right side of this operator in order for the document to be scored as a result.

The AFTER operator is also similar to NEAR.   The first term before this operator has to occur within a specified word distance AFTER the term on the right side of this operator in order for the document to be scored as a result.
