July 2025: Focused on improving search parsing and stability in nucliadb. Initiated a custom keyword query parser to enhance search accuracy and suggestions, refactored search-related modules, and added extensive tests, but rolled back the parser to the previous stable state due to regressions. Implemented a targeted workaround for Tantivy-related parsing changes with tests, and maintained high code quality through modularization and risk-based testing. The changes delivered measurable improvements to search reliability and maintainability, with a clear rollback plan to protect business-critical functionality.

June 2025 monthly summary focusing on key accomplishments in Graph API enhancements and SDK integration. Backend changes include enforcing a hard top_k limit of 500 in Graph search to improve resource management, and implementing a rebuild mechanism for boolean models in the Graph API, supported by tests for graph path queries using Pydantic models (AND, OR, NOT). A critical query parser bug was fixed to ensure proper parsing of filter operands, reducing edge-case query failures. In Nuclia Python SDK, Graph path query support was added via a new graph method on NucliaSearch to query the /graph endpoint, with accompanying documentation and tests. These updates collectively improve scalability, reliability, and developer experience, delivering concrete business value through more predictable search performance and easier integration.
