[fix](search) fix MATCH_ALL_DOCS losing occur attribute in multi-field expansion

[airborne12]

What problem does this PR solve?

Issue Number: close #DORIS-24561

Problem Summary:

In lucene mode with multi-field queries (e.g., best_fields with fields: ["title", "content"]), the query "Lauren Boebert" OR * returns results inconsistent with Elasticsearch.

Root cause: During multi-field expansion (expandNodeCrossFields, deepCopyWithField, setFieldOnLeaves), MATCH_ALL_DOCS nodes are recreated without preserving the occur attribute (e.g., SHOULD). The BE defaults occur=null to MUST, changing the query semantics:

• Expected (ES behavior): SHOULD(phrase) OR SHOULD(match_all) = all documents
• Actual (bug): SHOULD(phrase) AND MUST(match_all) = only phrase-matching documents

ES explain for "Lauren Boebert" OR *:

(title:"lauren boebert" | content:"lauren boebert") (ConstantScore(FieldExistsQuery [field=content]) | ConstantScore(FieldExistsQuery [field=title]))

Returns 1,000,000 docs (all). Doris was returning only phrase-matching docs.

Fix: Preserve the occur attribute when creating new MATCH_ALL_DOCS nodes in all three multi-field expansion methods.

Release note

Fix search() function returning incorrect results for lucene mode queries containing standalone wildcard * with multi-field expansion (e.g., "phrase" OR * with best_fields).

Check List (For Author)

• Test

  • Unit Test
  • Regression test
  • Manual test (add detailed scripts or steps below)
  • No need to test or manual test. Explain why:
    • This is a refactor/code format and no logic has been changed.
    • Previous test can cover this change.
    • No code files have been changed.
    • Other reason

• Behavior changed:

  • Yes. Multi-field lucene mode queries with standalone * (MATCH_ALL_DOCS) now correctly preserve the occur attribute during cross-field expansion, matching ES behavior.

• Does this need documentation?

  • No.

Check List (For Reviewer who merge this PR)

• Confirm the release note
• Confirm test cases
• Confirm document
• Add branch pick label
