 ## Summary
-TektonResults stores PipelineRuns, TaskRuns, Events as Records. Moreover, these are linked to parent object - PipelineRun or TaskRun via Results Table row.
-At present, there are no indexes created for querying these Records/Results. This propose a standard way in which Results can create certain indexes.

 ## Motivation
-Different platform have different annotations/labels which they use to filter out records.
-Results can't create predefined Indexes. They should be configurable via certain config.
-As a single row in Result Table has relation to many rows in Record Table, we should utilize Results Table to generate faster queries.

-Results Table row contains annotations and record summary annotations to integrate with different platforms. These platforms can communicate on what labels/annotations to store by these json values to annotation `results.tekton.dev/resultAnnotations` or `results.tekton.dev/recordSummaryAnnotations`.

 Now, Tekton Results can index all these four values.
 
 One more advantage of having these fields is we don't need to filter out based on `PipelineRun` if platform generates `PipelineRun` and needs to display values from `PipelineRun`.
