I have seen scenarios in which field-caps return information from outdated shards. While this is probably acceptable for most cases, ESQL query planning relies on field-caps, potentially leading to missing data. The reason for this is that we don't check readAllowed when not acquiring a searcher for cases without a filter. I don't expect too much penalty in terms of performance with this change, but it helps avoid a subtle issue for ESQL. Closes elastic#104809

@original-brownbear I checked the field-caps benchmark, and there have been no regressions. |
