Job-Set

The google algorithm is very intelligent you are getting your app in 25th ranking because algorithm search for the keyword in all categories and push the apps which has searched keyword in there name, high downloads and ratings to top. Because algorithm thinks from the user prospective it has to return all the type of apps in different categories because it doent knw what actually user is searching for.

Example:- If user is searching for a recorder which capture voice and He/She search for "Recorder" basically top apps will be Recorder keyword in there name and high downloads and rating from different categories also.(Check all the top 20 apps). This above search (Recorder) results include apps like Voice Recorder, Call Recorder, Screen Recorder so now this makes sense because algorithm doesnt know what actually user is searching for thats why it gives the results like that.

So thats why your app is ranking low when you search for keyword which is part of your app name. (If you search for you app name fully it should come first if it contains a unique name as you mentioned it should not be common keywords "Recorder").

Hope this answer will help many people to understand App store optimization.
