The “have” word might use as the verb, but I can not get any collocations for it where my query was just:
{
“query”:“have”
“lang”:“en”
“max_results”:“10"
“relation”:”"
“pos”:""
}

While I found a some examples with the word “have” here:
https://linguatools.de/kollokationen-en/bolls/?utf8=✓&lemmahits=100&query=have&commit=Search+Collocations!

Can you sort it out?
