Ontolica Preview uses crawl logs of SharePoint Search Service Application(s) as content sources to crawl and create preview images. In the Manage Content Sources page you will need to add one or more Search Service Applications as content providers.
When you click the New Content Source button on the toolbar the Add Content Source page will be opened. You will need to provide a name for the content source in the Content Source Name section. Ontolica Preview detects all available Search Service Applications in your farm and provides them in a drop-down list. In the Select Service Application section you will need to select a Search Service Application that will be used.
In the Default Content Access Account section you will need to provide credentials for an account that has Open, Read and Execute rights on the content from the selected Search Service Application. By default Ontolica Preview automatically gets the username of the default content access account for the selected Search Service Application, which can be found in the Central Administration > Application Management > Manage Service Applications > Search Service Application > Default content access account. The username of the account will be displayed in the Account textbox. You will need to provide the password for that account if you would like to use that account. You can also use another account. As Web page content and rendering is dependent on the account they are opened by, you can create two different content sources, one for documents and another one for Web pages. Then you can use two separate accounts for content sources. Alternatively this can be achieved by using Preview crawl rules.
On the same page you can furthermore configure Ontolica Preview performance settings, types of content to be crawled and also schedule time when the Ontolica Gatherer service will be crawling the content source. Each of these settings includes short description, along with instructions and also recommended settings. The Manage Content Source page contains short summary for each added content source. You can edit settings of a content source by clicking its name and selecting the Edit option from the drop-down list. The drop-down list also provides the Delete option to remove the content source.
