Phase 03 Plan 04: SearchService and DuplicatesService Summary

KQL file search with 500-row StartRow pagination (50k cap) and composite-key duplicate detection for files (Search API) and folders (CAML FSObjType=1)

Performance

• Duration: 2 min
• Started: 2026-04-02T14:09:25Z
• Completed: 2026-04-02T14:12:09Z
• Tasks: 2
• Files modified: 2 created

Accomplishments

• SearchService implements full KQL builder (extension, date range, creator, editor, library filters) with paginated retrieval up to 50,000 items
• DuplicatesService supports both file mode (Search API) and folder mode (CAML FSObjType=1) with client-side composite key grouping
• MakeKey logic matches the inline test scaffold from Plan 03-01 DuplicatesServiceTests — 5 pure-logic tests pass

Task Commits

Each task was committed atomically:

1. Task 1: Implement SearchService - 9e3d501 (feat)
2. Task 2: Implement DuplicatesService - df5f79d (feat)

Files Created/Modified

• SharepointToolbox/Services/SearchService.cs - KQL search with pagination, vti_history filter, regex client-side filter, KQL length validation
• SharepointToolbox/Services/DuplicatesService.cs - File/folder duplicate detection, MakeKey composite grouping, CAML folder enumeration

Decisions Made

• SelectProperties is a StringCollection — AddRange(string[]) does not compile. Fixed inline per-item foreach add loop (Rule 1 auto-fix applied during Task 1 first build).
• DuplicatesService re-implements file pagination inline rather than delegating to SearchService because result types differ (DuplicateItem vs SearchResult) and the two services have different lifecycles.
• MakeKey is internal static to match the test project's inline copy — enables verifying parity without a live CSOM context.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] StringCollection.AddRange(string[]) does not exist

• Found during: Task 1 (SearchService build)
• Issue: kq.SelectProperties.AddRange(new[] { ... }) — SelectProperties is StringCollection which has no AddRange taking string[]; extension method overload requires List<string> receiver
• Fix: Replaced with foreach loop calling kq.SelectProperties.Add(prop) for each property name
• Files modified: SharepointToolbox/Services/SearchService.cs, SharepointToolbox/Services/DuplicatesService.cs
• Verification: dotnet build 0 errors after fix; same fix proactively applied in DuplicatesService before its first build
• Committed in: 9e3d501 (Task 1 commit)

---

Total deviations: 1 auto-fixed (Rule 1 - bug) Impact on plan: Minor API surface mismatch in the plan's code listing; fix is purely syntactic, no behavioral difference.

Issues Encountered

• dotnet test ... -x flag not recognized by the dotnet test CLI on this machine (MSBuild switch error). Removed the flag; tests ran correctly without it.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• SearchService and DuplicatesService are complete and compile cleanly
• Wave 2 is now ready for 03-05 (Search/Duplicate exports) and 03-06 (Localization) to proceed in parallel with 03-03 (Storage exports)
• 5 MakeKey tests pass; CSOM integration tests will remain skipped until a live tenant is available
