Lucene query parser to ES Java API

Elastic Stack Elasticsearch
1

Is there a utility that can convert lucene query string format to ES Java
API format? We are planning to use lucene query parser to validate query
string entered by user in our application before creating a request to ES.

Not sure if much has changed since I asked a similar question a while back:

https://groups.google.com/forum/#!msg/elasticsearch/f4hE3lHsJeA/u0ovOO91Vr4J

Jorg's suggestion at the very end if perhaps the best, although I have
continued using my own method.

You may want to look at using the simple query string query instead:

It has the benefit of not throwing syntax errors, but trying to do the
right thing.

Yeah, don't try to wrap the query_string in piles of regexes to make sure
it never throws errors and blocks features you don't want but lets through
features you do. It isn't fun.

So suggestion is to just use java api simple query string object which I
presume uses same syntax as lucene?

I am still trying to figure this out on how I can do this using ES java
API. For eg: if user types the below search in the query string using
lucene syntax to our app server can I use this with ES Java API?
