Tala-med, an ad-free search engine, was developed to provide curated, expert-reviewed content with filters for trustworthiness, recency, user-friendliness, and comprehensibility. This study re-engineered the original system to overcome technical limitations while maintaining result consistency.\n                    <jats:bold>Methods:<\/jats:bold>\n                    A modular architecture was designed using Elasticsearch, a fastText-based synonym system, and a subZero-powered admin interface. The system was evaluated using 214 unique queries to compare performance and result similarity with the legacy version.\n                    <jats:bold>Results:<\/jats:bold>\n                    The new implementation improved query processing speed while preserving result consistency. Synonym handling was enhanced using fastText, and system maintainability increased via a centralized database and modular backend. The administrative interface simplified data updates and configuration tasks.\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    The re-engineered tala-med search engine maintains the original system\u2019s strengths while enabling greater scalability, flexibility, and future extensibility. The open-source platform offers a foundation for advancing domain-specific search systems and supports applications beyond the medical field.\n                  <\/jats:p>","DOI":"10.1177\/14604582251381271","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T21:20:04Z","timestamp":1758748804000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhancing medical information retrieval: Re-engineering the tala-med search engine for improved performance and flexibility"],"prefix":"10.1177","volume":"31","author":[{"given":"Florian","family":"Albrecht","sequence":"first","affiliation":[{"name":"Technical University Munich, Munich, Germany; School of Computation, Information and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruslan","family":"Talpa","sequence":"additional","affiliation":[{"name":"SubZero Cloud S.R.L, Oradea, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2067-5569","authenticated-orcid":false,"given":"Raphael","family":"Scheible-Schmitt","sequence":"additional","affiliation":[{"name":"Technical University Munich, Munich, Germany; School of Computation, Information and Technology"},{"name":"Technical University of Munich, Munich, Germany; TUM School of Medicine and Health, Department of Clinical Medicine, Institute of Artificial Intelligence and Informatics in Medicine, Chair of Medical Informatics; University Hospital rechts der Isar"},{"name":"Institute of General Practice, Faculty of Medicine and Medical Center, University of Freiburg, Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,9,24]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00103-020-03192-x"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2019.112552"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11606-019-05109-0"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/NT.0000000000000521"},{"key":"e_1_3_4_6_2","unstructured":"Eurostat.
