Exact matching of a whitespace followed by double quote and text gets broken into parts

Description of the bug

It seems I have run into an edge case with the exact matching. The SPACE_RE regex does not handle an edge case that from time to time occurs in my usage.

I managed to narrow it down to a string where a text is followed by a whitespace, followed by a double quote and then text. This gets erroneously split into two query parts on the whitespace, even though it was meant to be a single exact match query. I've set up a few tests at https://regex101.com/r/jlilH6/5 to try and wrap my head around it.

The Fuse.js version where this bug is happening.

6.6.2

Is this a regression?

• This is a regression bug

Which version did this behavior use to work in?

None

Steps To Reproduce

1. Run a search with the string ="said "test"
2. Set a breakpoint in the parseQuery(pattern) method
3. Observe item: "=\"said \"test\"" and query: ['="said', '"test"']

Expected behavior

I expected it to keep the exact match intact, and therefor to see at step 3 query: ['="said "test"']

Fixed in c226523. The SPACE_RE regex has been replaced with a proper tokenizer that correctly handles multi-match quoted tokens containing inner spaces and quotes.

="said "test" now correctly tokenizes as a single exact-match for said "test instead of being split into two tokens.
