Trace views do not return any data when no queries are specified

[VermaPriyanka]

What happened:
Trace views (list, span, service map) require a query expression to be specified to load any trace views. Unlike logs view, which by default would load all log entries for the data source when no query is specified.

What you expected to happen:
Either a pre-filled query to provide a landing experience or pre-load of an all results query, or some hint to the user that the results will appear only after the specify a query.

How to reproduce it (as minimally and precisely as possible):

• Configure an OpenSearch datasource, that has trace analytics enables.
• Go to Explore, and select the data source configured in prior step.
• Select Traces as query type, no results appear.
• Add a traceId:* query, results appear

Anything else we need to know?:

Environment:

• Grafana version: 10.4.1
• OpenSearch version: 2.15
• Plugin version: 2.18

Hi @VermaPriyanka,

I just tested it with plugin v2.18 and Opensearch v2.16 and I'm getting results with an empty query:

Could you paste the query displayed in the Query Inspector -> Query -> Copy to Clipboard so we can compare the queries? Thanks!
