If you think that the question doesn't show any effort to search the solution, then you can down-vote it.
Anyway, the fact that googling gives back links for the topic doesn't mean the OP didn't first search: The OP could have searched, but he didn't understand what he found. This could be because:
- The page is giving as implicit something the reader should already know; for example, if you look at the documentation page for a hook, that page will not remind you that the implementation of the hook is a function whose name is the hook name, where "hook_" is replaced with the short name of the module, followed by an underscore.
- The page is ambiguous, which could happen because the page is not complete, or because the user doesn't speak English as first language, and doesn't understand a particular construct used in that page. With this I am not saying that users who doesn't understand the basic English are excused for asking a question for which they would have found an answer by googling (then, if they don't understand the basic English, they would not understand the answer given on a SE site too), but I am not pretending that all users know the difference between English and english.
Users who search for an answer probably find links to pages for the exact argument they are looking for, but those pages could not refer to other pages that explain what necessary to understand the page being read.
Clearly, questions similar to "Can I use the Recipe module to write recipes?" doesn't make sense, as in the project page for the Recipe module is reported:
Recipe is a module for sharing cooking recipes. It includes support for taxonomy, CCK, views, and bulk import/export using common formats such as MealMaster, MasterCook, and RecipeML.
I agree that too much easy questions have a negative effect on a SE site, but
- the grade of difficulty of a question is not measured by the number of links Google returns
- a question is difficult depending from the knowledge of the user who asks it
I can find many links to the theory of relativity, but that doesn't mean all the questions about the theory of relativity are easy questions.
A question that is the equivalent of "What is the result of
1 + 1?" for the SE site about mathematic is clearly too simple, but it is also true that all questions seem easy for who knows much about a topic. For example, if you ask a question about Drupal core code to a Drupal maintainer, he is probably able to answer you without to search too much (especially if the question is about the part he is maintaining), while you could have looked hundreds of code lines without understanding what happens, and what the answer to your question is; this is particularly true for Drupal 7, where it is more difficult to follow which functions are called from another one (in particular, when the function invokes the method of a class whose name is found in a Drupal persistent variable).
