I maintained and developed ANSERA search engine for patents. I developed several custom plugins for Lucene and Elasticsearch (parsers, analyzers, tokenizers, token filters, aggregators, collectors) and data flow tools. I took part in the development of a custom query language for patent search. I did experiments to improve search relevance in the ERa (Enhanced Ranking) project using different evaluation metrics. I created REST micro-services. Currently I develop a search engine for non-patent literature (scientific papers, standards, etc. and their bibliographic data), written in different natural languages, which requires language detection, normalization and natural language specific analysis. For this purpose periodic research is done using KNIME analytics platform.

Search Engineer
Zaycev.net
2012-2015

The main responsibilities are to adapt Solr for the Russian language to use in http://zaycev.net. I configured Solr for the task of high-traffic (several millions queries a day) music search and developed several plug-ins: filters, parsers, customized scoring functions. I have developed a query log analyzer, which is used for comparison of changes, done in every sprint, while improving the search quality. I improved search experience in autocomplete, spellchecking, automatic correction of transliterated text or text typed using a wrong keyboard layout. I developed language models in Python and further implemented them in Java and Scala. I adapted fingerprinting music search (a-la Shazam) for the latest version of Solr.
