Proximity Operators

Proximity operators specify the relative location of specific words in the document; that is, specified words must be in the same phrase, paragraph, or sentence for a document to be retrieved. In the case of the NEAR and NEAR/N operators, retrieved documents are relevance-ranked based on the proximity of the specified words. When proximity operators are nested, the ones with the broadest scope should be used first; that is, phrases or individual words can appear within SENTENCE or PARAGRAPH operators, and SENTENCE operators can appear within PARAGRAPH operators. The following table describes each proximity operator.
