v0.7.0 - v0.7.11: can not determine when the exporting process has been completed

The new export((key, data) => ()) API that uses callbacks makes it impossible to know when the export-ing process is complete.

I’m having the exact same issue as @browniefed with export/import. There’s always zero results on the index doing the importing. I’m sure I’m doing something wrong, but I’m not sure what.

On a similar topic of import/export, I’ve got no idea why this would/wouldn’t work. It states that import is async but I cannot tell whether that is true or not as it just returns undefined rather than a Promise or a callback, or something.

Just in general I cannot seem to get import/export working with a filesystem or just in memory at all.

Basically my goal is to write write key as a filename and write the data, then at a future point import the index and do a search. That just doesn’t seem to work.

const { Index } = require("flexsearch");

const index = new Index();
const index2 = new Index();

// Loop and index bunch-o-content
index.add(item.title, content);


const result = index.search("textinput");

index.export((key, data) => {
// Just testing if we can recreate a search
  index2.import(key, data);
// Saving for future
  fs.writeFile(`./index/${key}`, data);
});

setTimeout(() => {
  const res = index2.search("textinput");
  console.log(result);
  console.log(res);
}, 1000);

// Index initial result // Index 2 no results even after import

[
// Returns results from initial Index
]
// res has no results even though we imported and did the same search.
