Constraints are a mechanism for modifying the behaviour of the query and are
|
|
divided into two classes (local or global) depending on the scope of the
|
|
modification. Local contraints may appear attached to each term in a query,
|
|
whereas global contraints apply to the entire query and so are listed after
|
|
the actual query (separated from the query by a colon).
|
|
|
|
This implementation supports the following constraints -
|
|
1. Local constraints
|
|
a. match=(exact|fuzzy)
|
|
The directory is either searched for an exact match of the value
|
|
specified or soundex style matching is attempted.
|
|
If you wish to attempt substring matching you should include a "*" in
|
|
your search string.
|
|
Default=exact
|
|
|
|
2. Global constraints
|
|
a. format=(full|abridged|handle|summary)
|
|
This specifies the format of the response returned by the query.
|
|
Normally the format used is controlled by the number of matches but this
|
|
constraint may be used to override the default.
|
|
b. hold
|
|
The connection is held open for a maximum of 60 seconds for further
|
|
queries, normally the connection is closed after each query.
|
|
c. language=<string>
|
|
Return any diagnostics in the natural language specified.
|
|
Default=english
|
|
d. linelength=<value>
|
|
This constraint allows you to indicate the maximum length of lines you
|
|
can display via your client.
|
|
Default=80
|
|
e. maxhits=<value>
|
|
The intent of this constraint is to limit the number of hits returned.
|
|
Unfortunately in the context of the server communicating with an X.500
|
|
server this is generally not possible as the DSA will define the
|
|
maximum number of entries it wishes to return. It is still of some use
|
|
if you wish to constrain the value to less than the value that the
|
|
X.500 directory would normally return.
|
|
The default value is dependant on the value configured by the Directory
|
|
Administrator into the DSA.
