Get Started with Demo Data

Load demo data to explore all VectrixDB features: semantic search, keyword search, reranking, and knowledge graphs.

Preparing...
Quick Start
5 min

Learn the basics: create a collection, add data, and perform your first search.

Steps:

1. Click Load Demo above
2. Go to Collections â†’ click `demo`
3. Browse the points to see the data
4. Go to Search and try all search modes

Semantic Search
Understanding meaning

Find results by meaning, not just keywords. Ask questions in natural language.

Try these queries:
How it works: Text is converted to vectors that capture meaning. Similar concepts cluster together in vector space.
Keyword Search (BM25)
Exact term matching

Traditional search that matches exact words. Great for names, codes, or specific terms.

Try these queries:
How it works: BM25 algorithm ranks documents by term frequency and rarity. Exact matches score highest.
Rerank Search
Dense + Re-ranking

Dense search with cross-encoder re-ranking for improved accuracy.

Try these queries:
How it works: Fast dense retrieval followed by precise re-ranking for better relevance.
Late Interaction
Late interaction

Token-level matching for maximum accuracy. Best for complex queries.

Try these queries:
How it works: Late interaction compares query and document tokens for fine-grained matching.
GraphRAG
Knowledge graph search

Automatically extracts entities and relationships, enabling graph-based retrieval.

Features:

- Auto entity extraction (People, Places, Concepts)
- Relationship mapping between entities
- Graph traversal for connected results

How it works: Uses the configured GraphRAG extractor (R default: regex) to build entity/relationship triples and a searchable knowledge graph.

# Code Tips

Copy-paste R examples for the VectrixDB R package. Click any code block to copy.

Quick Start (R)

Create a collection, add text, and search in a few lines.

click to copy

    library(VectrixDB)

    db <- Vectrix$new(
      name = "my_docs",
      path = "./vectrixdb_data",
      tier = "hybrid"
    )

    db$add(c(
      "R is excellent for data science",
      "VectrixDB provides semantic search in pure R",
      "Hybrid search combines dense and sparse signals"
    ))

    results <- db$search("semantic retrieval", mode = "hybrid", limit = 5)
    cat(results$top()$text, "\n")

Add metadata and filter results:

click to copy

    library(VectrixDB)

    db <- Vectrix$new("products", tier = "hybrid")

    db$add(
      texts = c("iPhone 15 Pro", "Galaxy S24", "Pixel 8"),
      metadata = list(
        list(brand = "Apple", price = 999, category = "phone"),
        list(brand = "Samsung", price = 899, category = "phone"),
        list(brand = "Google", price = 699, category = "phone")
      )
    )

    hits <- db$search(
      query = "premium phone",
      mode = "hybrid",
      filter = list(brand = "Apple"),
      limit = 3
    )

    print(hits$top())

Tiers and Modes
Collection Tier (set at creation)
dense vector search only
hybrid dense + BM25 + rerank
ultimate hybrid + late interaction
graph ultimate + knowledge graph workflow (regex extractor by default)
Search Mode (set at query time)
`dense` vector similarity
`sparse` keyword/BM25
`hybrid` dense + sparse + rerank
`ultimate` hybrid + late interaction
Language Behavior (set on collection)
`EN` English-focused tokenization + English stopword-aware reranking
`ML` Unicode-aware multilingual tokenization (no forced English stopword stripping)
Graph tip: `graph` is a collection tier. Query with `dense`, `sparse`, `hybrid`, or `ultimate`.
click to copy

    library(VectrixDB)

    # Create collections with different capability tiers
    x_dense <- Vectrix$new("docs_dense", tier = "dense")
    x_hybrid <- Vectrix$new("docs_hybrid", tier = "hybrid")
    x_ultimate <- Vectrix$new("docs_ultimate", tier = "ultimate")
    x_graph <- Vectrix$new("docs_graph", tier = "graph")

    # Optional: language-aware tokenization profile
    x_multi <- Vectrix$new("docs_multi", tier = "hybrid", language = "ml")

    # Run different search modes
    r_dense <- x_hybrid$search("query", mode = "dense")
    r_sparse <- x_hybrid$search("query", mode = "sparse")
    r_hybrid <- x_hybrid$search("query", mode = "hybrid")
    r_ultimate <- x_ultimate$search("query", mode = "ultimate")

Loading Data in R
From CSV

    library(VectrixDB)

    df <- read.csv("data.csv", stringsAsFactors = FALSE)

    meta <- lapply(seq_len(nrow(df)), function(i) {
      list(source = df$source[i], category = df$category[i])
    })

    db <- Vectrix$new("csv_docs", tier = "hybrid")

      name = "custom_docs",
      tier = "dense",
      embed_fn = my_embed,
      dimension = 128
