RecursiveCharacterTextSplitter
A text splitter provided by LangChain that recursively splits text by separators until chunk length matches the configured chunk size. It supports overlap settings to preserve contextual continuity and reduce semantic breaks.

Recursive character chunking traverses separators according to a priority list—paragraphs, line breaks, sentences, words, characters—and splits using the highest-priority separator under the premise that chunks do not exceed the limit.
VaultRAG's document ingestion flow is: the user uploads a PDF in the React interface, FastAPI receives the file, LangChain splits text chunks using RecursiveCharacterTextSplitter, then embedding vectors are generated via Ollama and stored in the local vector store.
The evolutionary spectrum of chunking strategies includes fixed-size splitting, sliding window splitting, recursive character splitting, and structure-aware chunking.
