Market locator missed markets

Hi,
I looked through this part of forum and find that many people have problems with Market locator and me too.
When I enter some text in Market name to search many markets are missed to be found. For example if I enter; Market name contains: penalty taken for Premier league,only on  couple matches  these markets are found, but these markets can be found on every premier league match. Any explanation for this?
It seems that Market locator needs some serious fix, as one of essential part of MFP, because in current state this part is pretty useless.

Unfortunately it's how the new API works - nobody can tells how the name search works... So that's how the new API answers for the search.
We are investigating the problem.

Yes I assumed there is some probem with new api. Same situation is with other markets(where custom text entered), so for example requested market is found on West Ham-Arsenal match but same market didn't found on Southampton-Chelsea. On every league some matches(markets) are missed, very strange
