When you configure text analytics for an indicator source, no data is available until a relevant data collector job is run. If you have newly created a text analytics configuration, run a special collection job. If you have added indicators to an existing text analytics configuration, run a historical data collection job to collect only text analytics.

• On the Setup Fields form, if the button is available next to Save, Update, and Delete, click Run collection.
  This button launches a single-use historical job that collects only text indexes. It is available only when you create a text analytics configuration.

  This job collects data for a period equal to the shortest period for which there is data for any of the indicators in the analysis. For example, if you are running text analysis on five indicators and you have one year of data for four of them but only four months of data for the fifth indicator, four months of text analytics are collected for all five indicators.

• If you have added an indicator to an existing text analytics configuration, configure and run a historical data collection job.
  1. Navigate to Data collection > Jobs.
  2. Create or edit a historical data collection job as described in Create or schedule a data collection job, with the following characteristics:
     • Set the Collect job parameter to Text indexes only.
     • Set the Run job parameter to On demand.
     • Set Relative start, Relative start interval, Relative end, and Relative end interval values that are appropriate for the indicators for which you are performing text analytics.
     • Ensure that the indicators for which you are performing text analytics match the indicators for the collection job.
  3. Execute the job.
