Answer 1

You cannot search for any item whose title contains #Yahoo. See: How to perform sql "LIKE" operation on firebase?

You can however search items whose title begins with #Yahoo:

Firebase firebase = new Firebase(Constants.FIREBASE_URL_USER_TASKS).child(Utils.encodeEmail(unProcessedEmail));

Query queryRef = firebase.orderByChild("title").startAt("#" + mHashTag)

To make this work well, you have to add an index to your Firebase rules:

"rules": {
  "userTasks": {
    "$email": {
      ".indexOn": "title" // index tasks in their title property
    }
  }
}
