Enterprise search technology is getting a fresh spotlight as exciting advancements in AI and natural language processing (NLP) make it easier than ever to find information across businesses. Since launching the first search engine in 1993, we've seen a major evolution in how we search for data. Today, innovative technologies are replacing old-school search tools, giving companies better ways to access and retrieve information.
This article will dive into some popular search techniques, showcasing their benefits and business use cases.
1. Retrieval-augmented generation
Retrieval-augmented generation (RAG) is a breakthrough AI search technology that combines the power of large language models with the accuracy of your business data. Unlike traditional AI that might "hallucinate" or make up information, RAG ensures responses are grounded in your verified data sources.
RAG is particularly valuable in enterprise environments where extracting insights from valuable datasets is critical. By using a retrieval mechanism, RAG searches through your internal app and tools to find relevant information, synthesize it, and generate accurate, contextual responses based on your trusted sources.
Example use case
Imagine your market research team needs to analyze competitor trends across three years of reports, customer feedback, and sales data. Traditionally, this would require hours of manual work across multiple systems. With Qatalog's RAG as a Service, simply ask "How has our market share changed in the premium segment since 2021?"
The RAG technology instantly retrieves relevant information across all connected sources (i.e., PDF reports, customer feedback from Salesforce, trends from BI tools) and delivers accurate, context-aware answers backed by your trusted data.
Key benefits
- Contextual relevance: RAG generates contextually relevant and informative text, improving the quality of responses.
- Fact-based accuracy: Reduces errors by grounding answers in verified information.
- Adaptability: RAG models are adaptable and can be fine-tuned for specific applications and business needs.
Why it matters for your business
The ability to quickly extract insights from your business information is crucial for making faster, data-backed decisions while leveraging all your existing data sources. RAG search technology reduces manual research time while maintaining accuracy and compliance.
Limitations
- Complex implementation: Requires specialist infrastructure and expertise in retrieval and generation techniques.
- Latency: Can introduce latency due to the retrieval process.
- Quality: The system's effectiveness depends on the quality of the retrieval process. If the retrieval process doesn’t find relevant information, the generation component might not produce the right responses.

Why it matters for your business
Qatalog's federated search improves productivity by consolidating information from different sources into one cohesive search experience, reducing the time it takes to find critical data.
Limitations
- Performance: May return too much data, requiring additional filtering to find relevant information.
- Data source compatibility: Data sources may use different search technologies, formats, and APIs, making integration and query processing complex.
- Security and access control: Federated search systems must handle security and access control for each source to ensure that users only see results they are authorized to access.
3. Semantic search
Semantic search goes beyond keyword matching, leveraging NLP to understand a search's intent and contextual meaning. It’s particularly useful for improving the accuracy of search results by interpreting user intent.
Today, semantic search covers a range of technologies and approaches. Some rely on intricate concept mapping to identify relationships between diverse entities. Others lean into contextual analysis to assess the backdrop against which a query is set. Vector search can also be used to enable semantic search.
Example use case
Semantic search powers web search engines, virtual assistants, and e-commerce platforms by understanding the meaning behind user queries, offering better recommendations and more relevant results.
Key benefits
- Improved relevance: Delivers results based on meaning and intent, not just keywords.
- Dynamic learning: Adapts to changes in language and terminology over time.
- Interconnected insights: By understanding relationships and context, it surfaces related information, even if it wasn’t explicitly searched for.
Why it matters for your business
With semantic search, your team can get more meaningful results, even when dealing with complex queries or evolving business terms.
Limitations
- Lack of precision: By attempting to understand context and relationships, semantic search can sometimes provide a breadth of information. For users seeking a narrow, specific answer, this can feel overwhelming and off-target.
- Data quality: Semantic search relies heavily on the quality of the data and may need to be combined with other search technologies to ensure it has access to the right information.
4. Vector search
Vector search, also known as similarity search, is a technique for identifying items in a large dataset that are similar to a specific query. This method gained traction in the early 2010s due to the rise of deep learning and neural network approaches.
In vector search, each item in a dataset (a word, number, or image) is represented as a high-dimensional vector, which is a numerical representation containing many dimensions. These vectors are stored in a large database, commonly referred to as a data index.
When you submit a query, it is also converted into a vector. The system then calculates the similarities between the query vector and the vectors in the dataset. The items with the highest similarity scores are ranked and presented as search results, allowing for quick identification of relevant information.
Example use case
Recommendation systems in e-commerce and personalized content engines use vector search to identify similar items and suggest relevant options to users.
Key benefits
- Versatile: Works for various data types, including text, images, or numerical data.
- Fast: Can process complex queries relatively quickly.
- Comprehensive: Allows for multi-modal search, such as finding images based on text descriptions.
Why it matters for your business
Vector search is ideal for businesses with vast datasets, ensuring fast and relevant recommendations, whether for customers or internal stakeholders.
Limitations
- Poor precision: As the number of data points increases, they can cluster too closely together, making it hard to find exact matches in large datasets.
- Data quality: The results of vector search depend on how well the data is represented. If the vectors fail to accurately capture the features of the data, the search results may be poor.
- Data security: Vector search requires storing all company data in a separate vector database that needs constant updates. This can increase the risks attached to data breach because research has shown that it’s possible to reverse-engineer vectors to reveal the original data.
5. Keyword search
Keyword search is the traditional and one of the most widely used search techniques. It works by using specific phrases to search through documents or records that contain those terms. Before a search is conducted, the content goes through an indexing process, which organizes the information for quick and efficient retrieval.
When keywords are entered into a search interface, algorithms activate and sift through the indexed content. This process produces a ranked list of matches, typically ordered by relevance, helping users find the most pertinent information quickly.
Example use case
Search engines, document management systems, complex databases, a more use keyword search to provide a ranked list of relevant matches based on user input.
Key benefits
- Simple and versatile: Simple, accessible, and highly flexible for a range of content types.
- Customizable: Allows users to control the search by adjusting keywords.
- Fast results: Quickly retrieves information based on specific terms.
Why it matters for your business
Keyword search remains effective for straightforward queries, especially in environments where users are looking for specific documents or records.
Limitations
- Relevance: Lacks understanding of context or intent, leading to irrelevant results.
- Overload: A broad keyword can generate too many results, leading to information overload.
- Missed information: Limited to exact matches, missing important data that uses synonyms or different phrasing.
6. Boolean search
Boolean search, rooted in mid-19th-century logic, has been essential for computer-based information retrieval since the mid-20th century. This technique uses logical operators—AND, OR, NOT—to create precise queries that filter search results.
Essentially, Boolean search establishes clear criteria. For example, using “AND” narrows the search to include both terms, like “cats AND dogs.” In contrast, “OR” broadens the search to include either term, such as “cats OR dogs.” The “NOT” operator excludes specific keywords, as in “cats NOT dogs.” By combining these operators with parentheses, users can perform more complex searches, such as “(cats OR dogs) AND birds.”
Example use case
Academic databases, job boards, and legal repositories frequently rely on Boolean search to filter and refine large datasets.
Key benefits
- Precision: Combines keywords and logical operators to create targeted results.
- Customization: Allows for complex queries to filter out irrelevant information in large databases.
- Good for large databases: Handles big datasets with ease.
Why it matters for your business
For businesses dealing with specialized queries or datasets, Boolean search helps cut through the noise to find the exact information needed.
Limitations
- Limited nuance: Boolean search isn’t sensitive to the nuances of natural language, which can become problematic if your keywords have close synonyms or variations.
- Time-consuming: Complex queries can be time-consuming to build and may require trial and error.
- Not intuitive: Requires users to be familiar with logical operators, which can be unintuitive for beginners.
