Channel Search does not search titles

[caffeinewriter]

Brief description
According to the v5 Migration Guide, I would expect the search/channels endpoint to search stream titles, especially with this wording in the migration notes.

The v5 endpoint searched for the channel title and category. Use “Search Channels” to match channel name or title. Use “Search Categories” to match a category.

Although according to the Search Channels API reference, the title searching functionality is less clear. If this is the intended behavior for the new API, it can hardly be considered a replacement for how v5 functioned previously.

How to reproduce
Search for a term that is popularly contained in titles, such as dixper or kappamon (two popular third-party stream extensions), or the name of a GTA V RP server like NewDayRP. E.g. With the twitch CLI:

twitch api get search/channels -q live_only=true -q query=dixper
twitch api get search/channels -q live_only=true -q query=NewDayRP

Expected behavior
search/channels returns streams with titles matching the query.

Screenshots
I've recorded a couple screen casts of the behavior:

Search for dixper
Search for NewDayRP

Additional context or questions
I reported an exceedingly similar issue for v5 in #515, and the issue with the search not including titles persists to Helix.

Yeah was gonna say 515 superseeds this based on the uservoice here

#515 (comment)

So 515 just needs moving to the helix label.

Or you can close 515 as you've made a duplicate

This is expected behavior. Any changes to this behavior are to be requested in the open User Voice:
