Text replace

Hi. What's the recommended way to index a transformation of a text (e.g. a summary, a title) and replace by the original text if retrieved? Constraint would be to have the original text not indexed. One use case would be to index table summaries but actually return the original tables after retrieval (but not index the original table, or at least have the tables not retrievable directly - only via their summaries). Thanks!

You could use a metadata replacement node postprocessor

https://docs.llamaindex.ai/en/stable/examples/node_postprocessor/MetadataReplacementDemo.html#querying

Or implement your own postprocessor that processes the retrieved nodes and replaces their text
