After 4 days app is still not indexed in Google Pl

I have published my first application (Voice To SMS) on google play 4 days ago and I still can't find my app in search by it's name or developer name. I can find my app only by package name or by real app name but without spaces - "VoiceToSMS".

Link to my app: https://play.google.com/store/apps/details?id=com.SpeechProcessing.Voice.To.SMS.Converter&hl=en

As we can see, in the bottom of the page there is no even "Similar apps" section...

In Google Play developer console everything seems OK (except that my app is not designed for tablets). 0 errors, I selected all available countries for distribution, app status is "Published". In app description I wrote some keywords.

What could be wrong? Maybe app is not indexed because its name is not specific?

I am attaching manifest.xml additionally:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.SpeechProcessing.Voice.To.SMS.Converter"

    </activity>

    <activity android:name="com.google.android.gms.ads.AdActivity"
         android:configChanges=

</application>
</manifest>

Well, more than 2 weeks gone after uploading my app on Google Play. My app is finally searchable by term "voice to sms". In my strong opinion, it wasn't Google-side issue that app wasn't searchable for a while by mentioned term.

I did one SEO trick - in app description I included some keywords whose are popular but not so like "voice to sms". In result, I got more downloads and growing my app's search rank. After few days, my app's rank was enough high that Google could show my app in results of "voice to sms" search term.

So, if you have similar problems - focus on SEO for your app.
