Joanchka,
Part of the problem MIGHT be that you need to read some posts that are in the general area of concern to see the words we use for that topic. I have found that sometimes the problem is an obscure topic, but more often it is that you are using words not commonly used for that subject matter. In other words, the jargon of this forum is often important in learning how to ask the right question.
The other part of the problem is that if you have a problem with, say, "recordsets" then when you search for "recordsets" you get eleven or twelve pages of hits - if not more. But if your problem is really a "type mismatch" in that recordset, choose the more restrictive term.
Sadly, a LOT of the problems in this forum have titles that don't help. Many folks say "This is not working" as a title, and in the search results page, all you see is a title. That does not help very much, does it? But it is a reality in the forum. All I can tell you there is to persevere and eventually you should be able to find something relevant.
Speaking of which, was this post started because you have a current problem and have not yet found what you wanted? Follow up in this thread and maybe we can point to some good search words or phrases for you.
