Describe the bug
query_ingesters_within didn't work as expected

To Reproduce
Steps to reproduce the behavior:

1. set reject_old_samples: false, query_ingesters_within=168h', max_chunk_age=2h`
2. Started Loki 3.2.1
3. Started Promtail 3.1.2 to tail logs with settings

            level:

3. Query: {job="training"} term

I imported some logs which were logged 4 days ago, and I hoped to query the logs immediately after I imported. I read this blog
According to my understanding, the logs of 4 days ago I justed imported has not yet be flushed, and with the default 'query_ingesters_within=2h' settings, the query searching logs for thoese logs will directly go to the store, which would match nothing.
SoI set query_ingesters_within=168h and the query (searching logs of 4 days ago)should be executed on the ingester (where the logs data exist currently). But still I return nothing. Only If I set both max_chunks_age= 168h and query_ingesters_within= 168h, It would return data.

Expected behavior
With setting query_ingesters_within= 168h, loki should return historical data immediately.

Environment:

• Infrastructure: bare-metal
• Deployment tool: mannully
