Architecture +**Decision:** Minimal Clone Pattern - create `oak-search-luceneNg` module (~60-80 files) following the Elasticsearch model. + +**Rationale:** +- Clean, maintainable codebase +- Proven pattern (Elasticsearch shows it works) +- No coupling to oak-lucene +- Easy to understand and maintain + +### 2. Module Name +**Decision:** `oak-search-luceneNg` + +**Rationale:** Follows the `oak-search-elastic` naming pattern. + +### 3. Property Names +**Decision:** +- `storeTargets` - Array of storage types to write to (e.g., `['lucene47', 'lucene9']`) +- `activeTarget` - The storage type used for queries +- `type` - Backwards compatibility fallback (if storeTargets/activeTarget missing) + +**Examples:** +``` +storeTargets = ["lucene47", "lucene9"] // Write to both +activeTarget = "lucene47" // Query from lucene47 +``` + +### 4. Storage Location +**Decision:** Implementation-specific storage locations: +- **Lucene 4.7:** Unchanged, uses `:data` under index definition +- **Lucene 9:** `/var/indexing/lucene//` (auto-created if missing) +- **Elasticsearch:** Remote cluster (unchanged) + +**Rationale:** +- Separation of concerns - definition vs storage +- Lucene 4.7 remains untouched +- Future implementations can choose their own strategy +- Clean namespace for each implementation + +**Path Derivation:** +```java +// Auto-derived for Lucene 9 +String storagePath = "/var/indexing/lucene/" + indexName; +``` + +### 5. Dependencies +**Decision:** No dependency on oak-lucene. Extract shared utilities to oak-search if needed. + +**Rationale:** +- Clean separation between implementations +- Avoids coupling and potential conflicts +- Forces proper abstraction of shared code + +### 6. Lucene Version +**Decision:** Lucene 9.x (likely 9.11.1 or 9.12.2) + +**Constraints:** +- Must stay on 9.x until Oak upgrades to Java 17 (Lucene 10 requires Java 17) +- Pure Maven dependencies only - NO embedded source code + +### 7. Upgrade Prevention Strategy +**Decision:** +- ✅ Pure Maven dependencies (no embedded code) +- ✅ Prefer public stable Lucene APIs +- ✅ Watch for version-specific leakage into higher layers +- ✅ Refactor if coupling appears (pragmatic, not dogmatic) + +**Rationale:** The 707 embedded files in oak-lucene made upgrades impossible. Never embed Lucene source code again. + +### 8. NRT Implementation +**Decision:** Defer to Phase 4 (research required) + +**Approach:** +- Phase 1-3: Async-only indexing +- Phase 4: Research native Lucene 9 NRT vs property index hybrid +- Deep dive into why property index hybrid was needed +- Prototype and compare approaches + +### 9. Query Safety +**Decision:** Fail fast with commit hook validation + +**Behavior:** +- When `activeTarget` is updated, commit hook validates: + - ✅ Target exists in `storeTargets` + - ✅ Target index is built and ready + - ❌ Reject commit if validation fails + +**Rationale:** Prevents accidental queries to unbuilt indexes, forces explicit control. + +### 10. Initial Build +**Decision:** Automatic async reindex when new target added + +**Behavior:** +- When a type is added to `storeTargets`, the async indexer automatically detects and builds that index from scratch +- Similar to how adding `async` property triggers reindex today + +### 11. Cleanup +**Decision:** +- Phase 1: Manual cleanup (data remains after removal from storeTargets) +- Future: Background async cleanup task (runs hours/days after removal) + +**Rationale:** +- Safe - allows rollback if issues discovered +- Removal from storeTargets is already a conscious decision +- Manual cleanup gives full control initially + +--- + +## Architecture + +### Module Structure + +``` +oak-search-luceneNg/ +├── pom.xml +│ └── Dependencies: +│ ├── org.apache.lucene:lucene-core:9.11.1 +│ ├── org.apache.lucene:lucene-queryparser:9.11.1 +│ ├── org.apache.lucene:lucene-analyzers-common:9.11.1 +│ └── oak-search (for common abstractions) +│ +└── src/main/java/.../luceneNg/ + ├── LuceneNgIndexProviderService.java ← OSGi service + ├── LuceneNgIndexDefinition.java ← Extends IndexDefinition + ├── LuceneNgIndexTracker.java ← Manages index lifecycle + │ + ├── index/ ← Write path + │ ├── LuceneNgIndexEditorProvider.java ← Implements IndexEditorProvider + │ ├── LuceneNgIndexEditor.java + │ ├── LuceneNgIndexWriter.java + │ └── OakDirectory.java ← Custom Directory for /var storage + │ + └── query/ ← Read path + ├── LuceneNgIndexProvider.java ← Implements QueryIndexProvider + ├── LuceneNgIndex.java + ├── LuceneNgPlanner.java + └── LuceneNgSearcher.java +``` + +### Key Components + +#### 1.
