Yes, these are 'searching for a text'
This type of question doesn't clarify what the definition is of Scripture / 'the Bible' (which is not agreed upon by site participants), and it is looking for other Bible passages to explain it rather than starting from the specific text being asked about and working outwards from there (i.e. 'searching for a text' rather than 'starting from the [specified] text').
However, most of these questions will never need to be closed, a simple edit can refocus them on the text being inquired about. Answers are always free to cite other texts in support of positions on the basis of various hermeneutics. E.g. instead of "how is this to be understood in light of Scripture?", they can simply ask, "how is this to be understood?" or "what does this mean?".
