Variables in RegEx & Is this an acceptable use for DGraph

Users

Hey @llonchj,

Thanks for the quick reply. I was missing the “p” I just had regex! Not regexp. :open_mouth:

So this works:

function query(usernamePartialString: string): string {
    return `query {
        users(func: regexp(username, /${usernamePartialString}/))
        {
            uid
            name
            emailAddress
            username
            timezone
            bio
        }
    }`;
}

when calling Dgraph....query(query('somestring'))

This however does not

const query = `query all($a: string) {
        users(func: regexp(username, /$a/))
        {
            uid
            name
            emailAddress
            username
            timezone
            bio
        }
    };`

when calling Dgraph.....queryWithVars(query, vars);

I get a Regular expression is too wide-ranging and can't be executed efficiently. Weird.

I can use the first method for now, so thanks again!
