+### Indexing
+The indexing is a pipeline for ingesting data and index it. This usually happens offline.
+1. We need to *load* the data. This can come from a variety of different sources
+2. We need to *split* the data into chunks because its easier for indexing and for passing it into a model.
+3. We need to *store* and index the splits such that we can search over them later. Examples are VectorStore and Embeddings model.
