Synonyms ranked higher than exact word

[jinyus]

Describe the bug
I have the synonyms pairs:

{
"hop" : ["jump"],
"jump" : ["hop"],
}

ranking rules:
"rankingRules": [
            "exactness",
            "words",
            "typo",
            "proximity",
            "attribute",
            "sort",
        ]

Whenever I search for hop I see all results for jump before results for hop even though exactness should outrank the synonym. Is this the expected behavior? If so: Is it possible to get the exact word to outrank its synonyms?

Hi @jinyus,
Thanks for the bug report, I could indeed reproduce the issue.
It's a mistake that a synonym is often treated as equally relevant to its original word. And it can also be fixed, although it won't be a trivial change. We're going to do a lot of deep work on the search algorithms in the coming weeks and months, and will keep this bug in mind in the process :-)
