# Index data

::::card-grid
:::card{title="Index data overview" href="/guides/index-data-indexing-overview"}
Learn how indexing works in Pinecone: serverless indexes, schemas, namespaces, integrated embedding, and metadata filtering.
:::

:::card{title="Data modeling" href="/guides/index-data-data-modeling"}
Model your data in Pinecone using documents with dense\_vector, sparse\_vector, full-text string, and metadata fields for efficient retrieval.
:::

:::card{title="Adopt the Documents API" href="/guides/index-data-adopt-the-documents-api"}
Learn what changes in API version 2026-07, whether your existing code is affected, and how to move to schema-based indexes.
:::

:::card{title="Search overview" href="/guides/index-data-search-search-overview"}
Compare Pinecone search types and choose the right retrieval approach: full-text (BM25), semantic (dense vector), sparse-vector, and hybrid.
:::

:::card{title="Semantic search" href="/guides/index-data-search-semantic-search"}
Search a Pinecone index of dense vectors to find semantically similar records using text or vector queries, top\_k results, and nearest neighbor lookup.
:::

:::card{title="Sparse-vector search" href="/guides/index-data-search-lexical-search"}
Run sparse-vector search in Pinecone with custom sparse encoders like pinecone-sparse-english-v0 for token-weighted keyword retrieval.
:::

:::card{title="Filter by metadata" href="/guides/index-data-search-filter-by-metadata"}
Narrow Pinecone search results by adding metadata filter expressions to your query, using operators like $eq, $in, $gt, and $and for precise retrieval.
:::

:::card{title="Rerank results" href="/guides/index-data-search-rerank-results"}
Improve retrieval quality by reranking initial search results with a hosted or external model to surface the most relevant matches for RAG.
