In a previous blog, the influence of the document format and the way it is embedded in combination with semantic search was discussed. LangChain4j was used to accomplish this. The way the document was embedded has a major influence on the results. This was one of the main conclusions. However, a perfect result was not achieved.
In this post, you will take a look at Weaviate, a vector database that has a Java client library available. You will investigate whether better results can be achieved.
