When you search for content, create a query statement that defines search criteria. To create a query statement, use operators such as the contains operator. For example, you can search for content that contains the title Mortgage.

The web service quick starts that correspond to the Document Management service (Deprecated) use the following WSDL:

http://localhost:8080/soap/services/DocumentManagementService?WSDL&lc_version=9.0.1
注意： Adobe is migrating Adobe® LiveCycle® Content Services ES customers to the Content Repository built on the modern, modular CRX architecture, acquired during the Adobe acquisition of Day Software. The Content Repository is provided with LiveCycle Foundation and is available as of the LiveCycle ES4 release.

    Summary of steps

    To search for content, follow these steps:

    1. Include project files.

    2. Create the service client.

    3. Define the query statement.

    4. Perform the search.

    5. Retrieve the search results.

    Include project files

    Include the necessary files in your development project. If you are using Java to create a client application, include the necessary JAR files. If you are using web services, include the proxy files.

    Add the following JAR files to your project’s class path:

    • adobe-livecycle-client.jar

    • adobe-usermanager-client.jar

    • adobe-contentservices-client.jar

    • adobe-utilities.jar (required if LiveCycle is deployed on JBoss)

    • jbossall-client.jar (required if LiveCycle is deployed on JBoss)

    注意： These JAR files are required if you are using the EJB connection mode. If you are using the SOAP connection mode, include additional JAR files.

    Create the service client

    Before you can programmatically retrieve content, establish a connection and provide credentials. This task is accomplished by creating a service client.

    Define the query statement

    To search for cotent, define a query statement by using one of the following operators:

    • JOIN_OPERATOR_AND

    • JOIN_OPERATOR_AND_NOT

    • JOIN_OPERATOR_OR

    • JOIN_OPERATOR_OR_NOT

    • OPERATOR_CONTAINS

    • OPERATOR_ENDS_WITH

    • OPERATOR_EQUALS

    • OPERATOR_GREATER_THAN

    • OPERATOR_GREATER_THAN_EQUALS

    • OPERATOR_LESS_THAN

    • OPERATOR_LESS_THAN_EQUALS

    • OPERATOR_STARTS_WITH

    When you use web services to search for conten, use a lucene query string. A lucene query string lets you search Content Services (deprecated). For example, to search for a PDF file named MortgageForm.pdf, specify the following lucene query string. 

        @cm\\:name:\"MortgageForm\"

    For information about creating lucene query strings, see Apache Lucene -- Query Parser Syntax.

    注意： When using the Java API to search for content, use a QueryImpl object, instead of a lucene query string.

    Perform the search

    After you define the query statement, you can perform the search by using the Document Management service’s searchRepository method. The results are returned in a com.adobe.livecycle.contentservices.client.ResultSet object.

    Retrieve the search results

    Iterate through the com.adobe.livecycle.contentservices.client.ResultSet object to retrieve the search results.

    Search Content Services (deprecated) content using the Java API

    Search content by using the Document Management Service API (Java):

    1. Include project files.

      Include client JAR files, such as adobe-contentservices-client.jar, in your Java project’s class path.

    2. Create the service client.

      • Create a ServiceClientFactory object that contains Java connection properties.

      • Create a DocumentManagementServiceClientImpl object by using its constructor and passing the ServiceClientFactory object.

    3. Define the query statement.

      • Create a QueryImpl object by using its constructor.

      • Create a StatementImpl object by using its constructor and passing the following values:

        • The fully qualified attribute name. For example, the fully qualified name attribute is {http://www.alfresco.org/model/content/1.0}name.

        • A StatementImpl enumeration value that specifies the search operation. For example, to use the contains operator, specify StatementImpl.OPERATOR_CONTAINS.

        • A string value that specifies the value to search for. For example, to search for a document with the name mortgageform, specify MortgageForm.

      • Attach the statement to the query by invoking the QueryImpl object’s addStatement method and passing the StatementImpl object.

      注意： For a complete list of attribute names, see Set content attributes.

    4. Perform the search.

      Perform the search by invoking the DocumentManagementServiceClientImpl object’s searchRepository method and passing the following values:

      • A string value that specifies the store name. The default store is SpacesStore. This value is a mandatory parameter.

      • A string value that specifies the path where the search is performed (for example, /Company Home). This value is a mandatory parameter.

      • A Boolean value that specifies whether to search sub-folders that are located in the specified path. The value true indicates to search sub-folders.

      • The QueryImpl object that represents the query statement.

      • An integer value that specifies the maximum value for the return set.

      The searchRepository method returns a com.adobe.livecycle.contentservices.client.ResultSet object that contains the search results.

    5. Retrieve the search results.

      Use the returned ResultSet object to retrieve the search results. You can determine the number of search results by invoking the ResultSet object’s getResultSize method.

    Search Content Services (deprecated) content using the web service API

    Search content by using the Document Management Service API (web service):

    1. Include project files.

      Create a Microsoft .NET project that uses MTOM. Ensure that you use the following WSDL definition: http://localhost:8080/soap/services/DocumentManagementService?WSDL&lc_version=9.0.1.

      注意： Replace localhost with the IP address of the server hosting LiveCycle.

    2. Create the service client.

      • Create a DocumentManagementServiceClient object by using its default constructor.

      • Create an DocumentManagementServiceClient.Endpoint.Address object by using the System.ServiceModel.EndpointAddress constructor. Pass a string value that specifies the WSDL to the LiveCycle service (for example, http://localhost:8080/soap/services/DocumentManagementService?WSDL.) You do not need to use the lc_version attribute. This attribute is used when you create a service reference.)

      • Create a System.ServiceModel.BasicHttpBinding object by getting the value of the DocumentManagementServiceClient.Endpoint.Binding field. Cast the return value to BasicHttpBinding.

      • Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding field to WSMessageEncoding.Mtom. This value ensures that MTOM is used.

      • Enable basic HTTP authentication by performing the following tasks:

        • Assign the LiveCycle user name to the field DocumentManagementServiceClient.ClientCredentials.UserName.UserName.

        • Assign the corresponding password value to the field DocumentManagementServiceClient.ClientCredentials.UserName.Password.

        • Assign the constant value HttpClientCredentialType.Basic to the field BasicHttpBindingSecurity.Transport.ClientCredentialType.

        • Assign the constant value BasicHttpSecurityMode.TransportCredentialOnly to the field BasicHttpBindingSecurity.Security.Mode.

    3. Define the query statement.

      Create a string variable and assign it a lucene query string value. For example, to search for a PDF document named MortgageForm, assign the string variable the value @cm\\:name:\"MortgageForm\. (See Apache Lucene -- Query Parser Syntax.)

    4. Perform the search.

      Perform the search by invoking the DocumentManagementServiceClient object’s searchRepositoryAPI method and passing the following values:

      • A string value that specifies the store name. The default store is SpacesStore. This value is a mandatory parameter.

      • A string value that specifies the path where the search is performed (for example, /Company Home). This value is a mandatory parameter.

      • A Boolean value that specifies whether to search sub-folders that are located in the specified path. The value true indicates to search sub-folders.

      • A string variable that represents the lucene query string.

      • An integer value that specifies the maximum value for the return set.

      The searchRepository method returns a ResultSet object that contains the search results.

    5. Retrieve the search results.

      Use the returned ResultSet object to retrieve the search results. You can determine the number of search results by retrieving the value of the ResultSet object’s resultSize field.
