On the Search landing page, you can configure which classes and class instances to index. You can also configure whether to index the contents of attachments. Enable attachment indexing only if your applications provide full-text search of work items. PDF, Microsoft Office, and text attachments are indexed and will be full-text searchable. However, if your application saves work item file attachments in an external enterprise content management system that is accessed through Connect CMS rules, such file attachments are not included in Pega 7 Platform search results.
On the Search landing page, you can aslo specify the maximum size of attachments to index. Attachments that exceed the threshold are not indexed and are listed in the log file.
You can configure indexing while a Pega 7 Platform server node is operating, however index processing can affect system performance if the indexes are large. As a best practice; choose a time when the server is less busy to perform these one-time processor-intensive operations.
Note: You can skip indexing of specific class instances by clicking Exclude this class from search? on the Advanced tab of the Class form. Excluded instances will not be included in search results.
