…62992) ### What problem does this PR solve? Issue Number: N/A Related PR: Problem Summary: Fix `score()` query failing on variant sub-columns with: ```text Index statistics collection failed: Score query is not supported without inverted index for column=<variant.subcolumn> ``` `MatchPredicateCollector::collect` previously used `TabletSchema::inverted_indexs(int32_t col_unique_id, const std::string& suffix_path)`, which only consults `_col_id_suffix_to_index`. Variant sub-column indexes can also live in: 1. `_path_set_info_map` (`subcolumn_indexes` / `typed_path_set`), when the parent variant index is inherited by sub-columns or a typed path index is materialized. 2. `_index_by_unique_id_with_pattern`, when the inverted index is created on the parent variant column with `PROPERTIES("field_pattern"="...")`. This PR fixes both paths: - Use the column-aware `TabletSchema::inverted_indexs(const TabletColumn&)` lookup so inherited / typed-path variant sub-column indexes are resolved. - Reuse the parent variant sub-column pattern matching logic from `variant_util` to resolve `MATCH_NAME` / `MATCH_NAME_GLOB` templates, then look up `inverted_index_by_field_pattern(parent_uid, matched_pattern)`. - Clone matched field-pattern index metadata and set the actual Lucene field suffix so score collection uses keys such as `<parent_uid>.<parent_col>.user.name`, while `CollectInfo::owned_index_meta` keeps the cloned metadata alive. Behaviour after this PR: | Scenario | Behaviour | | --- | --- | | Variant sub-column index is inherited or materialized in `_path_set_info_map` | Schema lookup succeeds through `inverted_indexs(const TabletColumn&)`; score collection uses the real sub-column Lucene field. | | Parent variant index uses exact `field_pattern`, e.g. `host` | Pattern lookup resolves the index and score collection uses `<parent_uid>.<parent_col>.host`. | | Parent variant index uses glob `field_pattern`, e.g. `user.*`, and slot path is `user.name` | Parent template matching returns `user.*`; index lookup uses the matched pattern; score collection uses `<parent_uid>.<parent_col>.user.name`. | | No index matches the sub-column | Existing unsupported-index error is preserved; BM25 score still requires an inverted index. | ### Release note Fix `score()` queries on variant sub-columns whose inverted index is inherited, typed-path based, or defined through `field_pattern`.
