Introduction
Today, we continue our series on the challenges of building RAG systems in the enterprise!
As discussed last time, a given company can use a very diverse set of sources. Microsoft SharePoint, Google Docs, Jira, Slack, and others are just a start. This means a lot of connector development work. It also brings a diverse set of data schemas and shapes. Coalescing all this data into a uniform system is an integral part of enterprise search platforms.
If you're a developer and new to the search world, it will be tempting to reach for the dynamic mapping capabilities of ElasticSearch or OpenSearch to index raw JSON quickly. While this “Schema-on-Read” flexibility is ideal for rapid prototyping, production-grade enterprise search requires the discipline of explicit mapping and strict schemas found in engines like Solr or Vespa. As seasoned relevance engineers know: if you don’t control your schema at the point of ingestion, you can’t control your precision at the point of retrieval.
While modern tools allow flexibility, enterprise RAG requires discipline. Over time, you’ll begin to see why enterprise search platforms like SOLR and Vespa rely on pre-defined, static schema. As data scientists and relevance engineers are fond of saying: it's all about the data!
In the following sections, we'll cover some approaches that help ensure effective search across many sources while enabling high-quality relevance across all use cases.
Key Takeaways
- Enterprise RAG requires sophisticated search capabilities beyond simple document retrieval, which demand careful normalization of diverse data sources across the organization.
- Language models perform best when paired with high-quality data and consistent schemas across enterprise sources such as SharePoint, Slack, and Jira.
- Search relevance dramatically improves when text fields are normalized for length and structure, ensuring consistent query response times.
- Vector search and similarity search work optimally with properly normalized metadata fields and structured content management
- Atolio's RAG solution outperforms competitors by providing superior information retrieval through advanced index optimization and cloud-native architecture.
Uniform Schema Across Sources: The Foundation of Enterprise Search
Spend time with your data. It's a lesson dispensed and learned over and over again. When you spend enough time with enterprise sources and APIs, you begin to see interesting patterns appear. These patterns can drive a standard schema in enterprise search systems.
As you bring new sources on board, you don't want to treat them each as unique and special. Instead, you can begin grouping them into classes. Some of our preferred classes include documents, tickets, and message bundles. Examples of document patterns include Microsoft Word, Google Docs, Atlassian Confluence, and loose PDFs. Another standard class is the ticketing system, such as Jira, Github Issues, Linear, and more. Messaging systems include Slack, Microsoft Teams, and so on.
These aren't the only classes you can find, but they are a good start and illustrate the goal. There's no perfect search schema, but you can eliminate many downstream problems by grouping your sources by class and driving them toward a standard schema like this. As the classes emerge, you'll start to see common fields such as title, author, date, people involved, and free text. We'll discuss the importance of common, consistent fields in the following sections.
Standard RAG Search and Language Models Integration
When implementing retrieval-augmented generation for enterprise environments, the integration between search systems and large language models (LLMs) becomes crucial. While some organizations attempt to use basic RAG search implementations, Atolio's approach provides a more comprehensive solution that understands the nuances of enterprise data structures.
The system leverages advanced LLMs to process queries, ensuring users receive contextually relevant responses intelligently. This integration requires careful consideration of how the search index interacts with the language model, particularly when dealing with complex operational data spread across multiple cloud environments.
Normalized Text for Relevance Foundations
As we noted in the last section, a standard schema will yield common fields, such as title, subtitle, body text, and so on. It's essential to minimize these core fields and their definitions for search implementation and efficiency. You'll keep your search queries and business logic from getting unwieldy. Even more important, you'll limit the number of variables your ranking algorithms must consider.
Digging deeper, you'll also want to start controlling text length. A two-page Word document versus a single Slack message can present significant hurdles for ranking and relevance. Fundamental lexical search algorithms, such as BM-25, are affected by text length. Newer semantic embeddings also require extensive investigation into techniques such as truncation, concatenation, and input chunking.
The gritty details are beyond the scope of this post, but in ideal scenarios, you begin to see a convergence of the source classes and the standard schema in pursuit of relevance. Your documents, tickets, and threads usually have titles with similar lengths. The ticket notes may be extracted and combined into a single text field for the search engine, more closely resembling documents. Messages may be conceptually bundled so that each source presents similar-sized batches of searchable text.
There's no one-size-fits-all solution for normalizing fields of text, but it's a topic you can't ignore.
Vector Search and Similarity Search Optimization
In modern enterprise RAG implementations, vector search has become an essential component for achieving high-quality similarity search results. Unlike traditional keyword-based approaches, vector embeddings enable the system to understand semantic relationships between content, dramatically improving the relevance of search results.
Atolio utilizes a high-performance Hybrid Search architecture, combined with its collaboration graph. By orchestrating these disparate scoring systems through a multi-stage Reranking pipeline, the system ensures that the most contextually relevant 'needles' are surfaced from the enterprise haystack, whether users are searching for exact matches or conceptually related content. The vector index is optimized for both speed and accuracy, providing sub-second response times even when searching across millions of documents.
Mapping Common Metadata Fields for Enhanced Data Quality
While text is important, let's not forget structured metadata either.
We've found that introducing each new source requires careful review and cataloging of the incoming fields. Every source treats users, dates, status, labels, and other common fields a little differently. It's real work to map all incoming fields to useful fields in your schema. Then, there's always a batch of fields that are truly unique to a source, and it's better if you don't leave them on the cutting room floor.
It sounds important, but what's the value? Fields with names and dates are essential for faceted search and analytics. General metadata is excellent for filtering and sorting. Then, when these are assembled in a unified schema and engine, you can combine such data queries with full-text search. This combination drives a rich set of use cases for both employees and AI systems.
Information Retrieval and Query Response Optimization
The heart of any enterprise search solution lies in its ability to deliver accurate information retrieval with minimal latency. Atolio's RAG solution excels in this area by implementing advanced query processing techniques that understand user intent and organizational context.
When a user submits a query, the system doesn't just perform a simple search. Instead, it analyzes the query structure, identifies relevant knowledge domains, and retrieves information from multiple sources simultaneously. This parallel processing ensures that responses are both comprehensive and timely. The system's ability to handle complex queries – including those with two or more conditional statements – sets it apart from basic search implementations.
One of the key advantages of Atolio's approach is its intelligent ranking of results. Rather than simply returning all matching documents, the system evaluates search relevance based on multiple factors, including recency, authority, and contextual importance. This ensures that users receive the most valuable results first, reducing the time needed to find critical information.
Enterprise RAG Implementation Best Practices
Successfully implementing RAG for enterprise search requires careful attention to several critical factors. First, organizations must ensure their data management practices support efficient indexing and retrieval. This means establishing clear governance policies and maintaining consistent data quality standards across all sources.
The integration between different system components is equally important. Your LLM needs seamless access to the search index while maintaining security boundaries and access controls. Atolio's cloud-native architecture addresses these challenges by providing secure, scalable integration points that respect existing enterprise security models.
Furthermore, the operational aspects of maintaining an enterprise RAG system cannot be overlooked. This includes regular index updates, performance monitoring, and continuous improvement of ranking algorithms based on user feedback and usage patterns.
