I'm seeing all items returned:

[
  {
    item: {
      auditLog: 'logs-1/.asjdfnjasbfa.json',
      author: 'John Scalzi',
      tags: [ 'fiction' ]
    },
    refIndex: 0
  },
  {
    item: {
      auditLog: 'logs-2/.ahjdfnjasbfa.json',
      author: 'Steve',
      tags: [ 'thriller' ]
    },
    refIndex: 1
  }
]

Fuse version: 6.4.3

@krisk I would think that only one item would be returned for a match on "logs-1"?

This is working as expected. If the search criteria is "logs-1", it will match both "logs-1" and "logs-2". Remember that Fuse is doing an approximate string matching (aka, fuzzy matching), and while "logs-1" is a perfect match, "logs-2" is a very close match nonetheless.

What would be the best way to get fuse to return only an exact match if there is one, likewise only return the partial matches if it can't find an exact?

[lmiller1990]

Anyone find a good config? I want to make something like the fuzzy finder in vscode - if I am looking for a file called log-1 with the query log-1, I do not want log-2 in my search results.

@lmiller1990 I think you're looking for something different to what fuse is doing. If I've understood correctly fuse is essentially about finding close misspellings, so you can search foo1 and find foo4 because it's similar. If you want something which is like the VSCode file matcher, it matches on exact content, but that content doesn't need to be consecutive. I don't think there will be a way to get Fuse to do that. Maybe there's a different package which does what you're looking for.
