Abstract: More than 20 thousand VO services are registered in the VO registry. Keyword Search is the most popular way to find a resource. There can be a lot of ways to implement this capability and the performance depends on how to index the document describing the resource metadata. We upgraded the registry service behind the Japanese Virtual Observatory (JVO) portal to be based on Apache Solr – which is an open source search platform that uses the Lucene Java search library for full-text indexing. Under the Solr environment documents are indexed after the process that removes stop words and stems the word to a root word. Solr also can handle single- or multi-token synonyms and abbreviation. The new JVO registry service has increased the probability for a given keyword to hit a desired resource metadata. The data from Nobeyama Legacy project were released from the JVO portal on 1st June in 2018 and they are now also distributed through the most recent VO standard interface called Simple Image Access version 2 (SIA-v2). The data of ALMA and Subaru telescope are also accessible through SIA-v2 access.
