I was thinking about making a "personal data search engine". I have almost 30GB of email archives and a bunch of Google Drive and offline files. I am thinking about downloading it all from the cloud and storing it on a large RAID array, with an indexing and search interface (and possibly a local MCP server).

Would Hister be suitable for this? Can it index mbox files? Would it handle this amount of data? Does it have a search API so I can build an MCP server?
