 To prepare large unstructured textual data (for example, a PDF or Word document), you first transform the data into plain text and then pass the resulting text through _Chunker_. The Chunker then splits the text into smaller chunks using a process known as **chunking**. A single document may be split into many chunks, each transformed into a vector.
