Feature Request: Integrate Apache Solr

[michaelwechner]

See https://solr.apache.org/guide/8_1/json-request-api.html

We could either write a connector, similar to

https://github.com/wyona/katie-backend/blob/main/src/main/java/com/wyona/katie/connectors/WeaviateSiteSearchConnector.java

or a question / answer handler, similar to

https://github.com/wyona/katie-backend/blob/main/src/main/java/com/wyona/katie/handlers/AzureAISearchImpl.java

curl http://localhost:8983/solr/INDEX_NAME/query -d '{"query" : "good recipe for lasagne"}'

It might make sense to use the Apache Solr Java client library https://solr.apache.org/guide/8_1/using-solrj.html

One can now query Apache Solr using the Third Party RAG connector

JSON Pointer for reference node implemented

Consider developing a dedicated connector similar to
