Jay-ju opened a new pull request, #67051:
URL: https://github.com/apache/doris/pull/67051

   ### What problem does this PR solve?
   
   Lance regular scans currently leave common string predicates and direct 
boolean predicates in Doris, so Lance cannot filter rows before Arrow 
materialization and transfer.
   
   ### What is changed?
   
   - Push two-argument `LIKE` / `NOT LIKE` predicates without backslash escapes 
through the existing Substrait filter.
   - Push `starts_with(column, literal)` and `ends_with(column, literal)`.
   - Push direct boolean-column predicates, including `NOT boolean_column`.
   - Keep explicit/custom LIKE escapes, REGEXP, non-literal patterns, and 
non-string inputs as Doris residual predicates.
   - Extend FE unit and external Lance regression coverage.
   
   ### Testing
   
   - `mvn -pl fe-core -am -Dtest=LancePredicateConverterTest 
-DfailIfNoTests=false test` (21 passed)
   - `test_lance_scalar_predicate_pushdown` against local MinIO + FE + BE
   - Manual end-to-end LargeUtf8 `starts_with` verification
   
   ### Release note
   
   Improve Lance predicate pushdown for common string and boolean expressions.
