Bug: When using Mem locally, search::highlight('<b>', '</b>', 1, true) does not support the fourth parameter

[maoly1012]

Describe the bug

When using Mem locally, search::highlight('', '', 1, true) does not support the fourth parameter, and the error is "Incorrect arguments for function search::highlight ()." Expected 3 arguments ".

Steps to reproduce

`use serde::{Deserialize, Serialize};
use surrealdb::engine::local::Mem;
use surrealdb::sql::Thing;
use surrealdb::Surreal;
#[derive(Debug, Serialize)]
struct Person<'a> {
title: &'a str,
name: &'a str,
marketing: bool,
}

#[derive(Debug, Deserialize)]
struct Record {
#[allow(dead_code)]
id: Thing,
}

#[tokio::main]
async fn main() -> surrealdb::Result<()> {
// Connect to the server
let db = Surreal::new::(()).await?;
// Select a specific namespace / database
db.use_ns("test").use_db("test").await?;
db.query("DEFINE ANALYZER ngram_search TOKENIZERS blank, class, punct FILTERS lowercase, ngram(1,10)")
.query("DEFINE INDEX ngram_search_index ON person COLUMNS title SEARCH ANALYZER ngram_search BM25 HIGHLIGHTS").await?;
// Create a new person with a random id
let created: Vec = db
.create("person")
.content(Person {
title: "Founder & CEO",
name: "Morgan Hitchcock",
marketing: true,
})
.await?;
dbg!(created);
// Perform a custom advanced query
let groups = db
.query("SELECT title, search::highlight('', '', 1, true) as high FROM person where title @1@ 'Founder'")
.await?;
dbg!(groups);
Ok(())
}`

Expected behaviour

response title "Founder & CEO" and the highlight title

SurrealDB version
