+ "Search or modify authentication backends according to SPEC.
+
+This function parses `auth-sources' for matches of the SPEC
+plist. It can optionally create or update an authentication
+token if requested. A token is just a standard Emacs property
+list with a :secret property that can be a function; all the
+other properties will always hold scalar values.
+
+Typically the :secret property, if present, contains a password.
+
+Common search keys are :max, :host, :port, and :user. In
+addition, :create specifies how tokens will be or created.
+Finally, :type can specify which backend types you want to check.
+
+A string value is always matched literally. A symbol is matched
+as its string value, literally. All the SPEC values can be
+single values (symbol or string) or lists thereof (in which case
+any of the search terms matches).
+
+:create t means to create a token if possible.
+
+A new token will be created if no matching tokens were found.
+The new token will have only the keys the backend requires. For
+the netrc backend, for instance, that's the user, host, and
+port keys.
+
+Here's an example:
+
+\(let ((auth-source-creation-defaults '((user . \"defaultUser\")
+ (A . \"default A\"))))
+ (auth-source-search :host \"mine\" :type 'netrc :max 1
+ :P \"pppp\" :Q \"qqqq\"
+ :create t))
+
+which says:
+
+\"Search for any entry matching host 'mine' in backends of type
+ 'netrc', maximum one result.
+
+ Create a new entry if you found none. The netrc backend will
+ automatically require host, user, and port. The host will be
+ 'mine'. We prompt for the user with default 'defaultUser' and
+ for the port without a default. We will not prompt for A, Q,
+ or P. The resulting token will only have keys user, host, and
+ port.\"
+
+:create '(A B C) also means to create a token if possible.
+
+The behavior is like :create t but if the list contains any
+parameter, that parameter will be required in the resulting
+token. The value for that parameter will be obtained from the
+search parameters or from user input. If any queries are needed,
+the alist `auth-source-creation-defaults' will be checked for the
+default prompt.
+
+Here's an example:
+
+\(let ((auth-source-creation-defaults '((user . \"defaultUser\")
+ (A . \"default A\"))))
+ (auth-source-search :host '(\"nonesuch\" \"twosuch\") :type 'netrc :max 1
+ :P \"pppp\" :Q \"qqqq\"
+ :create '(A B Q)))
+
+which says:
+
+\"Search for any entry matching host 'nonesuch'
+ or 'twosuch' in backends of type 'netrc', maximum one result.
+
+ Create a new entry if you found none. The netrc backend will
+ automatically require host, user, and port. The host will be
+ 'nonesuch' and Q will be 'qqqq'. We prompt for A with default
+ 'default A', for B and port with default nil, and for the
+ user with default 'defaultUser'. We will not prompt for Q. The
+ resulting token will have keys user, host, port, A, B, and Q.
+ It will not have P with any value, even though P is used in the
+ search to find only entries that have P set to 'pppp'.\"
+
+When multiple values are specified in the search parameter, the
+user is prompted for which one. So :host (X Y Z) would ask the
+user to choose between X, Y, and Z.
+
+This creation can fail if the search was not specific enough to
+create a new token (it's up to the backend to decide that). You
+should `catch' the backend-specific error as usual. Some
+backends (netrc, at least) will prompt the user rather than throw
+an error.
+
+:delete t means to delete any found entries. nil by default.
+Use `auth-source-delete' in ELisp code instead of calling
+`auth-source-search' directly with this parameter.
+
+:type (X Y Z) will check only those backend types. 'netrc and
+'secrets are the only ones supported right now.
+
+:max N means to try to return at most N items (defaults to 1).
+When 0 the function will return just t or nil to indicate if any
+matches were found. More than N items may be returned, depending
+on the search and the backend.
+
+:host (X Y Z) means to match only hosts X, Y, or Z according to
+the match rules above. Defaults to t.
+
+:user (X Y Z) means to match only users X, Y, or Z according to
+the match rules above. Defaults to t.
+
+:port (P Q R) means to match only protocols P, Q, or R.
+Defaults to t.
+
+:K (V1 V2 V3) for any other key K will match values V1, V2, or
+V3 (note the match rules above).
+
+The return value is a list with at most :max tokens. Each token
+is a plist with keys :backend :host :port :user, plus any other
+keys provided by the backend (notably :secret). But note the
+exception for :max 0, which see above.
+
+The token's :secret key can hold a function. In that case you
+must call it to obtain the actual value."
