Step 1. Launch Aspire / Go to Content Source Management

  1. Launch Aspire (if it's not already running).
  2. Open the Content Source Manager page.
  3. Browse to: http://localhost:50505.
    • For details on using the Aspire Content Source Manager page, go to Admin UI.




Step 2. Add a Twitter Connector Content Source

To specify exactly which shared folder to crawl, we will need to create a new "Content Source".

To create a new content source:

  1. From the Content Source, click Add Source.
  2. Click Twitter Connector.


Step 2a. Specify Basic Information

In the General tab in the Content Source Configuration window, specify basic information for the content source:

  1. Enter a content source name in the "Name" field. 
    1. This is any useful name that you decide is a good name for the source. It will be displayed in the content source page, in error messages, etc.
  2. Click the Scheduled pull-down list and select one of the following: Manually, Periodically, Daily, Weekly or Advanced.
    1. Aspire can automatically schedule content sources to be crawled on a set schedule, such as once a day, several times a week, or periodically (every N minutes or hours). For the purposes of this tutorial, you may want to select Manually and then set up a regular crawling schedule later.
  3. Click the Action pull-down list to select one of the following: Start, Stop, Pause, or Resume.
    1. This is the action that will be performed for that specific schedule.
  4. Click the Crawl pull-down list and select one of the following: Incremental, Full, Real Time, or Cache Groups.
    1. This will be the type of crawl to execute for that specific schedule.

After selecting a Scheduled, specify the details, if applicable:

  • Manually: No additional options.
  • Periodically: Specify the "Run every" options by entering the number of "hours" and "minutes."
  • Daily: Specify the "Start time" by clicking on the hours and minutes drop-down lists and selecting options.
  • Weekly: Specify the "Start time" by clicking on the hours and minutes drop-down lists and selecting options, then selecting the day check boxes to specify days of the week to run the crawl.
  • Advanced: Enter a custom CRON Expression (e.g. 0 0 0 ? * *)
 
You can add more schedules by clicking the Add New option, and rearranging the order of the schedules.

If you want to disable the content source just clear the the "Enable" checkbox. This is useful if the folder will be under maintenance and no crawls are wanted during that period of time.

Real Time and Cache Groups crawl will be available depending on the connector.


Step 2b. Specify the Connector Information

In the "Connector" tab, specify the connection information to crawl with the Twitter Connector.

  1. Enter the "Consumer Key" produced in the prerequisites section
  2. Enter the "Consumer Secret" produced in the prerequisites section.
  3. Specify all the "Twitter User(s)" you want to crawl.
  4. Use Fixed ACLs: Select if you want to use a fixed ACL that will be attached to all of the the documents fetched
    1. Users: Fixed user ACLs
      1. Domain: User's domain
      2. Name: Username
      3. Type: Select between Allow and Deny
    2. Groups: Fixed group ACLs
      1. Name: Group's name
      2. Type: Select between Allow and Deny



Step 2c. Specify Workflow Information

In the "Workflow" tab, specify the workflow steps for the jobs that come out of the crawl. Drag and drop rules to determine which steps should an item follow after being crawled. This rules could be where to publish the document or transformations needed on the data before sending it to a search engine. See Workflow for more information.

  1. For the purpose of this tutorial, drag and drop the Publish To File rule found under the Publishers tab to the onPublish Workflow tree.
    1. Specify a Name and Description for the Publisher.
    2. Click Add.
  2. After completing these steps click Save and Done.
    • You'll be sent back to the Home page.



Step 3: Initiate a Full Crawl

Now that the content source is set up, the crawl can be initiated.

  1. Click on the crawl type option to set it as "Full" (is set as "Incremental" by default and the first time it'll work like a full crawl.
    • After the first crawl, set it to "Incremental" to crawl for any changes done in the repository).
  2. Click Start.


During the Crawl

During the crawl, you can do the following:
  1. Click on the "Refresh" button on the Content Sources page to view the latest status of the crawl.
    • The status will show RUNNING while the crawl is going, and CRAWLED when it is finished.
  2. Click on "Complete" to view the number of documents crawled so far, the number of documents submitted, and the number of documents with errors.

If there are errors, you will get a clickable "Error" flag that will take you to a detailed error message page.



Step 4: Initiate an Incremental Crawl

If you only want to process content updates from the Aspider Web Crawler (documents which are added, modified, or removed), then click on the "Incremental" button instead of the "Full" button.

  • The Aspider Web Crawler connector will automatically identify only changes which have occurred since the last crawl.
  • If this is the first time that the connector has crawled, the action of the "Incremental" button depends on the exact method of change discovery.
  • It may perform the same action as a "Full" crawl crawling everything, or it may not crawl anything. Thereafter, the Incremental button will only crawl updates.


Statistics are reset for every crawl.
