Hi,
I'd like to prepare new query parser which will be triggered for each query
sent to ES.
I already implemented a query parser and attached it to AnalysisService but
I have to run it by
{
"query" : {
"custom\_query : {
....
}
}
}
I'd like to avoid this. ES has multiple clients for multiple languages but
not all of them support such a custom query type.
Is it possible to trigger my custom\_query parser for each query sent to ES?
I see that I can build my own RESTAction but it means the endpoint will
change (\_search =\> \_custom\_endpoint) so again it can be not supported by ES
clients.
Do you have any suggestions how to handle this?
