Advanced query example?

I’m trying to use FlexSearch for building a search that acts a lot like the lucene language, so support for logical operators (using either AND, NOT or +, - respectively as well as OR), quotes/exact phrase match (“foo bar” won’t match the text “bar foo”).

From the README’s supported features table it looks like FlexSearch can do that, but I couldn’t seem to get it to work using even a “wasteful” configuration, as well as a basic query:

const index: Index<string> = FlexSearch.create({
  tokenize: 'full',
  encode: 'extra',
  stemmer: false,
});

index.add(1, 'foo');
index.add(2, 'bar');
index.add(3, 'foo bar');
index.add(4, 'bar foo');

const values = index.search([
    { query: 'foo' },
    { query: 'bar' },
]); // values is an empty array

If I use the string overload of search: index.search('foo bar') it does find id 3 and 4, but how can I specify that only one of them is required for example, or that the I want the full query as a phrase (i.e. id 3 is valid, 4 is not).

So, a couple of questions:

1. Am I missing something?
2. Is what I want to do even possible with FlexSearch? If so, how can I achieve that? Ideally I’d just configure the operators in the create() call, and then search() can parse it automatically based on that.

@ts-thomas I didn’t see that issue on my previous search. Too bad it’s not supported. I voted for it there anyway, and this issue and upvotes and attention it received strengthens that it’s a needed (wanted) feature 😃. I hope it’s taken into account as a feature request in a future release. This is what we wanted to use Flexsearch (or others) for.

Please change over to the version >= 0.7.x, thanks a lot.
