Description

some kind of helper tool that translates from an Elasticsearch / Solr / Lucene query to YQL / query API, possibly combined with supporting documentation in https://vespa.ai/migrating-from-elastic-search-to-vespa - this will make it easier to do apples-to-apples comparisons for users doing evaluations

Contributor guide

Research direction
Familiarize yourself with Elasticsearch query DSL and Vespa YQL. Look at existing query parsers in the Vespa codebase for reference. Consider starting with a simple mapping for basic queries and then extending.
