Can we find items which includes "my search string" in the middle of text, e g - find a search term which includes spaces?

Searching for *cloudportal*
/admin/items?term=*cloudportal*
will successfully find this word anywhere within any item.

Now i need to search in the same way but with a space between cloud and portal.

Searching for *cloud portal* 
/admin/items?term=*cloud%20portal*
is the same as searching for cloud portal as
/admin/items?term=cloud%20portal
and will find items where _either_ cloud or portal exists.

Searching for "cloud portal"
/admin/items?term=%22cloud%20portal%22
will make it only find items where a field is exactly "cloud portal" with nothing before or after

So how can we search for the string "cloud portal", including the space, within another string, e g myString.includes("cloud portal")?
Searching for *"cloud portal"*
/admin/items?term=*%22cloud%20portal%22*
is not a valid syntax and finds all items
