Sorry for the direct ping, but I believe this bug could potentially have Lance to return results from unintended fragments. This might have broader implications so I want to bring this to your attention, thanks. |

…quested fragments (#5924) Fixes bug where vector and FTS searches ignore `with_fragments() `filter when querying unindexed fragments, which will return results from indexed fragments that were not requested. Note, this does not fix the issues where `with_fragments` contains both indexed_fragement and non_indexed_fragment for FTS and vector search, and I have a separate follow up PR to fix the behavior. This PR combines my previous effort for fixing the issue: #5081 #5080 --------- Co-authored-by: stevie9868 <yingjianwu2@email.com>

Vector search currently does not respect the target fragment list specified via Scanner.with_fragments().
Given a dataset with:
Scenario 1: Query targets only unindexed fragments [4, 5]
Scenario 2: Query targets mixed fragments [3, 4]
