In my opinion, there is and should be a different standard for "research" between EL&U and ELL. I look for effort and context, not research. Have you ever tried to Google anything about 'in' or 'of' without knowing the terminology that's relevant to your question? There are some very common questions that come up when learning English that are very difficult to research if you aren't fluent, and some that are tough even for fluent folks to find supporting sources for what they know intuitively.
I look for explanations of/links to where they saw what they're asking about, what meaning they think it has (or would like it to have if it's a request), and just in general some effort to make their question clearer. I really dislike questions where the question is in the title, and the body is essentially "see title" and close vote them whenever I come across them. You could at least copy and paste your title into the body, yeah?
I think that one of the strengths of ELL is that the questions are asked in the way a learner writes them, and that might make it easier for other learners to find answers if they have a similar question. We should encourage learners to explain their questions in their own voice and help them enough so that the question is clear without rewriting it to make it perfectly grammatical. It's intimidating for some folks to write in a language they don't know well, which is why I think we need to be a kinder, gentler SE.
Sometimes voting to close the question gets it the attention it needs to get shaped up so we can re-open it and provide useful answers. Unfortunately, too many people see closing a question as something irreversible or a judgment of the author and not of the post.
