17.4 Using proximity operators with searches in text fields
Proximity operators offer the opportunity of searching with a higher precision, compared to the Boolean operators
AND, OR, NOT, by searching for the terms entered only within a certain scope (e.g. in one field, in one sentence, or
within a specified distance). The way proximity operators are used is different between the databases with a
segmented structure and other databases, possibly with special features in any of the databases. Therefore help is
available in all of the databases (HELP (S), HELP (P), HELP (L) ).
In literature databases and in most patent databases with static or dynamic concept proximity operators are used
like this:
