Search with exact: true doesn't work as intended

[zeroliu]

Describe the bug

When I search with exact: true, documents with partially matching terms are also returned.

To Reproduce

https://codesandbox.io/p/sandbox/lvy7mc

const db = create({
schema: {
path: "string",
title: "string",
},
});

insert(db, { path: "First Note.md", title: "First Note" });
insert(db, { path: "Second Note.md", title: "Second Note" });

const noExact = search(db, {
term: "first",
properties: ["path"],
}); // 1 result OK
const withExact = search(db, {
term: "first",
properties: ["path"],
exact: true,
}); // 1 result NOT OK

console.log("noExact path", noExact);
console.log("withExact path", withExact);

Expected behavior

Calling search with exact: true should only return documents with terms that exactly matches.
