Strange regexp behavior

Hi Michel,

What “i am actually doing” i described in my first message but can repeat once again.
In my front-end(browser) i have an input field to put in user’s full name(second first middle) to search users and a table to see a result(list of users or maybe empty list). Further, i want to see a result on every character i put in. The query(neo4j cypher) in my first message is from a real project. I couldn’t find how to do that for dgraph, so i asked if it is possible. Sorry.

<<This only can be achieve by https://docs.dgraph.io/query-language/#regular-expressions>>

Yes, i read it. But the regexp only works if patterns are longer than 2 characters and this is not suitable for my case. What is a reason not to have a “normal” regexp?
