go:embed

[mikejsavage]

bleve only exposes an API to open a search index by filename.

It would be nice if you could make an index from a []byte instead so you could embed a precomputed index. For a concrete use case: I would like to ship a geocoding DB with my app and embedding it is the most robust way to do that.

Alternatively, here's a variation of your proposed solution/change that would work well along side the existing //go:embed directive:

Add a new function OpenFS with the following signature:

import "io/fs"

func bleve.OpenFS(fs.FS) (Index, error)

Combined with embed.FS this would allow you to embed a precomputed index directory at build time, e.g.:

import "embed"

//go:embed geocodingdb.bleve/**
var indexFS embed.FS

Then when the program starts, parse it in memory:

index, err := bleve.OpenFS(indexFS)
