Installing Neo4j Graph Database Desktop Version
- By Bruce Nielson
- ML & AI Specialist
Last time in our series of AI tutorials, we covered how to install Neo4J (graph database). For the Mindfire stack, we’re aiming to stick with open-source software, and Neo4j Server Community Edition fits the bill. However, there’s also a free Enterprise edition available (with some limitations) if you use Neo4J Desktop, which we'll be looking at today.
Installing Neo4J Graph Database Self-Managed for Retrieval Augmented Generation (RAG)

In previous posts, we learned how to install PosgreSQL and then how to install pgvector (a vector search extension for PostgreSQL.) The Book Search Archive (our toy app to show off Mindfire’s growing low-cost open-source AI stack) currently utilizes a PostgreSQL database with vectors handled by pgvector to do our semantic searches using a HNSW index built-into pgvector. In this post, we'll be looking at how to use Neo4J, a graph database with vector support, to do RAG.
AI Tutorial: Hybrid Search in Detail

Looking to make your AI a bit more personable or easier to communicate with? In today's article by Bruce Nielson, we'll be testing out some ways of making an LLM have text-to-speech functionality using the Hugging Face framework.
PDFs vs HTML: The Importance of Metadata for Retrieval Augmented Generation
- By Bruce Nielson
- ML & AI Specialist
In our ongoing series of AI tutorials, we have been focusing on using EBUP documents instead of PDFs. In today's article, we will dive a bit into the reasons for why that is, and the differences between PDFs and HTML documents when it comes to AI frameworks. We also have a look into how you can use PDF documents with AI.
Implementing a Lexical Search
- By Bruce Nielson
- ML & AI Specialist
In a previous post, our expert on AI, Bruce Nielson, discussed how to run a hybrid search using AI wherein we could merge a lexical search and a semantic search together to create single higher quality result. Today, we will dive into how to conduct just a lexical search as to better showcase the differences.
Hybrid Search for Retrieval Augmented Generation

In a previous blog post, we introduced our "Book Search Archive," which we have been using to experiment with using AI to search and extrapolate information. In today's blog post with Bruce Nielson, we'll be discussing "hybrid searches" to better improve upon our AI model and showcase the power of an AI-driven search.
Our Open-Source AI Stack: The Book Search Archive
- By Bruce Nielson
- ML & AI Specialist
For much of this year, we have been publishing blog articles that showcase how to create an AI powered search and query engine that can extrapolate information or answers to questions directly from archived books, specifically the Federalist Papers. In today's article, we have a quick re-cap of what we have so far accomplished.
An AI Tech Support Agent

Large companies love to talk about AI and how they are trying to incorporate it into their business model. However, especially for smaller companies, some business owners may assume that there just isn't any real use for AI in their industry, causing them to feel like they are falling behind everyone else in modernizing their company. In today's article by Bruce Nielson, we'll dive into one real-world example of how any business can take advantage of AI: An AI Tech Support Agent.
