Is this possible with the current websearch_to_tsquery function?

Thanks.

    Hello everyone, I am wondering if
    AROUND(N) or <N, M> is still possible? I found this thread below and
    the original post
    https://www.postgresql.org/message-id/fe931111ff7e9ad79196486ada79e268%40postgrespro.ru
    mentioned the proposed feature: 'New operator AROUND(N). It matches
    if the distance between words(or maybe phrases) is less than or
    equal to N.'

    currently in tsquery_phrase(query1 tsquery, query2 tsquery, distance
    integer) the distaince is searching a fixed distance, is there way to
    search maximum distance so the search returns query1 followed by
    query2 up
    to a certain distance? like the AROUND(N) or <N, M> mentioned in the
    thread?

As far as I know AROUND(N) and <N, M> weren't committed, unfortunately. And so you can search only using a fixed distance currently.

websearch_to_tsquery() can't help here. It just transforms search pattern with OR, AND statements into tsquery syntax.
