Searching for a traceId in grafana / jaeger does not work after 3 days.

[uptickmetachu]

Describe the bug
Versions:
quickwit v0.8.2
Grafana v11.8.3
jaegertracing/jaeger-query:1.53.0

Datasources:

• 1 jaeger datasource against jaeger query
• 1 jaeger datasource against quickwit (api/v1/otel-traces-v0_7/jaeger)

I make a search for a trace in grafana explore against a trace_id and I can see it. A few days later I cannot find the trace via the jaeger search (whereas I can still find it via the quickwit datasource).

I manually test trace Ids and I've isolated that traceIds fail to be searched (via jaeger) exactly after 3 days.

Expected behavior
I expect the trace to still be viewable via the quickwit viewer after a few days.

Configuration:
Please provide:

1. Output of quickwit --version
2. The index_config.yaml

Actually I found the conversation on discord about jaeger config
lookback_period_hours which defaults to 72hours which matches this experience but unfortunately isn't documented anywhere on the website.

I'm assuming we configure it via:

jager:
   lookback_period_hours: XXX

And inside the helm chart:

config:
  jager:
    lookback_period_hours:

[uptickmetachu]

I guess the intention is to limit the lookback period once a trace has been found. The problem is that this isn't working as intended and is excluding the trace ID if it doens't even land within the lookback period.
