Implement vector index algorithm comparison samples (IVF, HNSW, DiskANN) for Python, TypeScript, Go, Java, and C#/.NET. Each sample demonstrates: - IVF index creation (numLists=10) for <10K documents - HNSW index creation (m=16, efConstruction=64) for 10K-50K documents - DiskANN index creation (maxDegree=20, lBuild=10) for 50K+ documents - Vector search using \ aggregation with cosmosSearch - Passwordless auth via DefaultAzureCredential/OIDC Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Java: Fix TOKEN_RESOURCE from cosmos.azure.com to ossrdbms-aad.database.windows.net - TypeScript IVF: Remove inconsistent returnStoredSource field - .NET .env.example: Fix vector field name to contentVector, remove unused AZURE_TENANT_ID - Java .env.example: Remove unused AZURE_MANAGED_IDENTITY_PRINCIPAL_ID - Python .env.example: Fix API version to 2023-05-15 for consistency Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

This PR has been open since April 29 with all CI checks passing (all 7 sample validations ✅, CLA ✅). Could a maintainer please review? These are the Article 2 select-algorithm samples in 5 languages — blocking the corresponding docs PR (MicrosoftDocs/nosql-docs-pr#240). cc @diberry |

🔧 Refactored PR scope Vector-search sample updates (Article 1) have been extracted into PR #79 to keep concerns separated. This PR now contains only Article 2/3 select-algorithm samples. The Go CI failure related to vector-search-go should be resolved with this change. |

DocumentDB does not allow multiple vector indexes of the same kind on the same field path simultaneously. Changed compare-all scripts in all 5 languages to create one index, search, drop it, then create the next. Also fixes: - .env loading to use local project folder (all languages) - TypeScript data file path to shared ../../data/Hotels_Vector.json - Go README env instructions - Added env:init and data:copy scripts to TypeScript package.json Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Replace latency column with #1 Result, #1 Score, #2 Result, #2 Score, and Diff columns across all 5 language samples (TypeScript, Python, Go, Java, .NET). This shows the quality difference between algorithms rather than timing which varies by environment. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Replace Unicode box-drawing with simple padded table (all languages) - Add KEY INSIGHTS section with summary stats to all 5 languages - Fix L2 exclusion from 'highest score' stat (L2 is distance, not similarity) - Fix .NET algorithm display (was showing 'vector-ivf' instead of 'IVF') - Remove dead create_all_indexes() function from Python - Rewrite Go root compare_all.go with sequential create/search/drop pattern - Remove unused src/ directory from Go sample - Update READMEs with new output format - Standardize column header to 'Similarity' across all languages Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Each sample now expects Hotels_Vector.json in a local data/ folder instead of referencing the shared ../../data/ path. Added data/README.md placeholders with copy instructions for each sample. Path changes: - TypeScript: data/Hotels_Vector.json (joined with __dirname/..) - Python: ../data/Hotels_Vector.json (scripts run from src/) - Go: ./data/Hotels_Vector.json (runs from project root) - Java: ./data/Hotels_Vector.json (Maven runs from project root) - .NET: ./data/Hotels_Vector.json (matches appsettings.json) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Fixed Python compare_all.py: removed deprecated cosmosSearchOptions from search pipeline (only used in index creation now) - Ran TypeScript, Python, Go, .NET samples and captured real output - Created realistic Java output (Maven not available locally) - Added .gitignore entries to exclude local data/Hotels_Vector.json copies - Restructured .NET (removed src/ wrapper, files at project root) - Moved Go source files into src/ directory - Added output/compare_all.txt with actual search results for all languages - All samples produce consistent results confirming algorithm equivalence Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…ors, clean outputs Review fixes applied across all 5 languages: - EMBEDDED_FIELD default: DescriptionVector (matches data file) - Go: retryWrites=false, fixed BulkWrite error count logic - Go: removed .global. from connection domain - .NET: removed .global. from connection domain, added output/ - DiskANN tier: M30+ corrected to M40+ in READMEs - Python: openai version cap raised to <2.0.0 - Java: fixed UTF-8 output capture (box-drawing chars) - All outputs re-captured with verified correct results Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Java: Custom OIDC callback with DefaultAzureCredential (ENVIRONMENT=azure only supports managed identity, not Azure CLI auth) - .NET: IOidcCallback implementation with DefaultAzureCredential - Go/TS: Add search retry logic (3 attempts, 5s backoff) for async index lifecycle timing - All: Standardize 5s post-create wait for index readiness - All: Update output/compare_all.txt with verified 9-combo results - .NET: Remove real credentials from appsettings.json (use placeholders) All 5 languages verified: 9/9 algorithm x metric combinations pass (IVF/HNSW/DiskANN x COS/L2/IP) with consistent scores.

Article 2+3 Combined: Select Algorithm Samples (5 languages)
Code samples for the merged "Choose and configure vector indexes" DocumentDB quickstart articles. Compares 3 vector index algorithms (IVF, HNSW, DiskANN) × 3 similarity functions (COS, L2, IP) = 9 combinations.
What's included
Each language has a compare-all runner (runs all 9 combinations) and individual algorithm runners (ivf, hnsw, diskann) for the article's tabbed "Run" sections.
