Add a weblib Knowledgebase

User role: System Administrator

Web crawling enables administrators to make outside knowledge sources accessible to users and reduce administration costs. With this feature, you can:

  • Index and search external Web content, such as RightAnswers and Microsoft's TechNet.
  • Index and search Intranet content, such as internal corporate web content.

If you have large number of documents that you do not want to import into Service Manager but still wish to index and search, you can publish these documents to a web server for crawling with the web crawler. You can also crawl these documents with the file system crawler.

Indexing requirements for web crawling

The indexing requirements for a weblib-type knowledgbase are different than those of an sclib type. For weblib types, Service Manager stores only information used to create the knowledgebase (collection) format and the information used by the search engine to index the pages being crawled.

Log files for web crawling

Log files are generated during indexing for the web pages being crawled. These log files are located in the following directory:

C:\Program Files (x86)\HPE\Service Manager x.xx\Search_Engine\kmcrawler\logs

The log files end in .log.

The two most important log files in this folder are skipkeys.log and joberror.log. The skipkeys.log provides detailed information as to why a particular page was skipped during indexing. For example, if a page is an excluded mime type or if the path depth has been exceeded, it is logged in this file. The joberror.log contains the errors encountered by the indexer. For example, if you provided a start URL that could not be reached, it is logged here.

To add a new weblib knowledgebase, you need to complete the following tasks.

Task 1: Add a weblib type knowledgebase record.

To add a weblib type knowledgebase record:

  1. Click Knowledge Management > Configuration > Knowledgebases.
  2. Type a unique name for the new knowledgebase in the Knowledgebase name field (required). For example, My_Web.
  3. Type a display name for the knowledgebase (required). For example, My Web.
  4. Select weblib in the Type field list.

  5. Click Add.

    The knowledgebase record is added. Continue to configure the tabs of the record and test the knowledgebase, as described in the following tasks.

Task 2: Configure the Type information tab.

The Type Information tab maintains information about the knowledgebase's source and security. Configure the following Type information settings.

Field Description
URLs

URL: Type the URLs in the space provided. You can enter more than one URL, but use only one URL per line.
Note: The "http://" prefix is required for all URL's. For example: http://www.bbc.com
URL path depth

Limits indexing to the specified number of path segments in the URL or file system path. The default is 100 path segments.

The path length is determined as follows:

  • The host name and drive letter are not included. For example, neither www.spider.com:80/ or C:\ are included in determining the path length.
  • All elements following the host name are included.
  • The actual file name, if present, is included. For example, /world.html is included when determining the path length.
  • Any directory paths between the host and the actual file name are included.

    For example: For the following URL, the path length would be 4: http://www.spider:80/comics/fun/funny/world.html

    where:
    comics = 1 segment
    fun = 1 segment
    funny = 1 segment
    world.html = 1 segment
Max links to follow

Specifies the maximum number of levels from the starting URL that an indexing includes. If you see extremely large numbers of documents in a knowledgebase where you do not expect them, consider experimenting with this option, in conjunction with the Content options, to reduce the reach of the index.

Specify a number between 0 and 255. The default is 255, which is equivalent to there are no limits on the number of jumps.
Constrain indexing to host domains By default, links are not followed outside the hosts provided in the URLs. Un-checking this box lets the indexer index outside the hosts specified.
Mime Types
  • Unlimited: The search engine supports over 1,200 different MIME types. Selecting "Unlimited" will include this full list of MIME types during crawling.
  • Include:List the MIME file types to be included in the index. Specify the file type by using the MIME specification. Enter only one MIME type per line.
    You may use the "*" wildcard only for MIME types. For example, "text/*". This example will include all the MIME types that start with "text/".
  • Exclude: List the file types NOT to be included in the index. Specify the file type by using the MIME specification. Enter only one MIME type per line.
    You may use the "*" wildcard only for MIME types. For example, "text/*". This example excludes all the MIME types that start with "text/".

    The default values in the drop-down list for MIME types can be configured as follows:

    1. Go To Tailoring > Database Manager.
    2. Search for the kmmimetypes table to retrieve the full list of MIME types. Note: You can edit the list of MIME types. See Edit the List of MIME Types.
    3. Check the Mimelist box, so that the all available MIME types will appear in the drop-down list.
    4. Save your changes.
Proxy Configuration
  • Proxy Host: Provides the proxy host name when the web site being crawled uses a proxy server.
  • Port: The port number used by the proxy server.
  • Username: The user name required by the proxy server for access. This may not be required for all proxy servers.
  • Password: The password associated with the user name provided. This may not be required by all proxy servers.
Security Scripts
  • Knowledgebase access script: This script specifies the script the system uses to determine if a particular user has rights to access the knowledgebase. See the default script for more detailed information.
  • Search security script: This script further limits what the user has access to when accessing the knowledgebase. This script returns a query string that is added to the user's normal query to limit the scope of the particular user's access to documents in the knowledgebase. See the default script for more detailed information.
  • Category index script: This script processes the document category so that the indexer can translate the document’s category into a string that the search engine can use later to find the document based on the user’s category access.
  • Advanced search script: This script processes a string of library-specific query values using the KMQuery object. The values in KMQuery were entered by the user under the tabs in the Advanced Search screen. You can tailor this script if this knowledgebase has a tab in the Advanced Search screen.
  • Default locale: Specifies the default language used by the search engine when searching and indexing. By default, the language code matches the language you logged in as.

Task 2: Configure the Status tab.

The Status tab for a weblib knowledgebase displays information about the selected knowledgebase's index. This information includes the following:

Field Description
Master, Slave, or Load Balancer

This field provides information about the search servers that are connected to the selected knowledgebase. Details on each server connection include type of server (Master, Slave, or Load Balancer), state of the server, date the server was created, and the number of documents that were indexed in the knowledgebase. For more information, see the State, Created, and Docs settings.

To make changes to a search server, go to Knowledge Management > Manage Search Servers and select the search server.
State Indicates whether the knowledgebase is on-line, off-line, or replicating (if it is a slave server). If State is blank, the knowledgebase is either off-line or the search engine is not connected. If the knowledgebase has not been created, this field is blank.
Created Displays the knowledgebase creation date and time. If the knowledgebase has not been created, this field is blank.
Docs Displays the number of documents contained in the index. If the knowledgebase has not been created, this field is blank. If the knowledgebase has been created but not indexed, this field will show 0 documents.
Status Since the index is created separately from the knowledgebase creation, the Status field displays the current status of the index. Values can be "Not Created," "Created," "Running," and "Finished."
Schedule this index? You can choose to schedule the index to start on a particular day and time. Select the Schedule this index? check box to enable scheduling.
Start Date Select the first day you wish this index to run. Adjust the time values to the time of day the index should run.
Frequency

You can schedule the index to run once, hourly, daily, weekly, or monthly.
For example, if you scheduled the index to run on Monday, May 5, at 6 p.m. and selected an hourly frequency, the index would run the first time on Monday, May 5, at 6 p.m. and would then run again at 7 p.m., 8 p.m., and so on until you updated the schedule.

Note: When indexing, the search engine only indexes documents that have changed since the last run.
Crawler Host

Specify the host name of a search server for web crawling. It can be a master or slave search server; however for optimized performance you can use a dedicated server for crawling only.
Crawler Port Specify the Tomcat port of the crawler host.

The tab also includes buttons for indexing.

Button Description
Initialize Index Once you have all your settings specified for a new knowledgebase, click this button. The system sends the settings to the search engine. The search engine creates the empty knowledgebase for index. After a knowledgebase and index have been created, click this button to erase the index and create an empty knowledgebase. You should create a new knowledgebase if you change the parameters on either the Type information tab or Field Definitions tab.
Start Indexing Click this button to start an index manually. Instead of scheduling index updates, you can use this button if the file system you are crawling does not change or if you want to test index settings once.
Stop Indexing Click this button to stop an indexing process that is running. Click the Start Indexing button to resume indexing from the point where the index was stopped. To start indexing from the beginning, click Initialize Index.
Refresh Statistics When selected, the search engine refreshes the statistics of the indexing process to show how many documents are indexed and searchable at that time in the process.

Task 3: Index the weblib knowledgebase.

  1. On the Status tab, click Initialize Index.
  2. Click Start Indexing.

  3. Click Refresh Statistics to monitor the indexing status. Once the documents have been indexed on the crawler and replicated to the searcher, you can continue to perform a test search on the weblib knowledgebase.

    The following figure shows an example.

Task 4: Search in the weblib knowledgebase.

Perform a search in the new weblib knowledgebase to verify that it is set up properly.

  1. Click Knowledge Management > Search Knowledgebase.
  2. In the Search In section, select only the new weblib knowledgebase.

  3. Enter a search word in the search box, and click Search.

    The following figure illustrates a list of search results of an example weblib knowledgebase.
