A word or an idiom for not wanting to look into something else to not get sidetracked [duplicate]

Example:

In this article about bugs I focus primarily on 7-legged bugs and purposely not consider spiders as it would require me to [look into and explain the details I don't want to here] them which is not the point here.

In a way, it's close to to dirty one's hands with smh but without a negative connotation.

I'm quite confident there's a word for it, but I just can't remember it. I think to dip into is close, but too casual (slang-ish), I'm looking for something for more formal writing.


"To look into something else" and "get sidetracked" is to fall down a rabbit hole.

Merriam-Webster calls a rabbit hole

a...situation...in which the pursuit of something (such as an answer or solution) leads to other questions, problems, or pursuits


You don’t want to be distracted:

dis·tract (dĭ-străkt)

tr.v. dis·tract·ed, dis·tract·ing, dis·tracts

  1. To cause (someone) to have difficulty paying attention to something: The voices in the other room distracted him, so he couldn't concentrate on his homework.

  2. To attract (the attention) away from its original focus; divert.

  3. To cause to feel worried or uneasy; unsettle: The company's workforce was distracted by the prospect of a takeover.

The second definition is the most pertinent, as it notes that you want to keep the focus on the current topic.

It is common to use the phrase “beyond the scope” when describing the content of a paper and also setting out the limits of your discussion. See this discussion on Academia Stack Exchange: https://academia.stackexchange.com/questions/143708/beyond-the-scope-of-this-paper-phrase

So, I would reword your example sentence as follows:

In this article about bugs, I focus primarily on 7-legged bugs. Spiders are beyond the scope of this article.

(Just curious: What 7-legged bugs???)
