C. Field level and proximity search operators
These operators are more restrictive
types of the logical AND operator and are in particular useful for text
searching
The field level and proximity search operators
are:
(G)
 same field (all occurrences of a repeatable field are treated as A single
entity for example:
water (G) soil  will retrieve all records with both water and soil provided
that they occur in the same field.
(F)
 same field or individual, occurrence of a repeatable field.
Water (F) soil will retrieve all records
with both water and soil in the same field or the same occurrence of a
repeatable field ((G) and (F) are equivalent when applied to non repeatable
fields):
.
as (F) but with the additional restriction that the terms are no more than
n words apart. Where n is the number of periods plus one for example:
A . B  adjacent
A . . B at most one word between
A and B

A . . . B at most two words between
A and B
$
as (F) but with the additional restriction that the terms are exactly n
words apart, where n is the number of dollars plus one. For example:
A $B adjacent
A $$B exactly one word between A
and B
A$$$B exactly two words between
A and B
Note that the operators and $ must be preceded
and followed by one space.
