The following relational operators compare text and match words and parts of words:
Operator Description
CONTAINS Selects documents by matching the word or
phrase that you specify with the values stored in
a specific document field. Documents are
selected only if the search elements specified
appear in the same sequential and contiguous
order in the field value.
MATCHES Selects documents by matching the query
string with values stored in a specific document
field. Documents are selected only if the search
elements specified match the field value
exactly. If a partial match is found, a document
is not selected. When you use the MATCHES
operator, you specify the field name to search,
and the word, phrase, or number to locate. You
can use ? and * to represent individual and
multiple characters, respectively, within a string.
STARTS Selects documents by matching the character
string that you specify with the starting
characters of the values stored in a specific
document field.
ENDS Selects documents by matching the character
string that you specify with the ending
characters of the values stored in a specific
document field.
SUBSTRING Selects documents by matching the query
string that you specify with any portion of the
strings in a specific document field.
For example, assume a document field named SOURCE includes the following values:
•
Computer
•
Computerworld
•
Computer Currents
•
PC Computing
To locate documents whose source is Computer, enter the following:
SOURCE <MATCHES> computer
To locate documents whose source is Computer, Computerworld, and Computer Currents, enter
the following:
SOURCE <MATCHES> computer*
