What is the best way to search for conferences all over world? I need to participate in one in the near future.
By doing reasonable googling. As you didn't state your topic let me make an example when searching for conferences on magnetism. The operators I use should be self-explaining. Most conferences will be announced on websites of universities or mentioned, to exclude old ones search only within
2014..2014, and so on...

I have a very good experience with national and similar subject mailing lists, for instance French "Groupes de Recherche" such as http://www.gdr-im.fr/ intended for Theoretical Computer Science. There're dozens of them in France for instance.
Once you are a member of such group, you recieve quite a lot of mail (subject prefixed by
[gdr-im]), most of it are information on interesteing seminars, job offers and conference CfP (for both local and international meetings). I have found being a member of this mailing list very valuable.
Nature's website has a list of scientific conferences and events (324 events are listed in September 2014), but may be biased towards certain fields. I think I saw similar lists in other journals as well.
I worked as an administrator for the 21st McGill International Entrepreneurship conference and we listed our conference on a conference announcement directory called PaperCrowd.
It attracted several delegates from around the world. I found out it was in the same city I lived in and I applied for a job there and got it! I am now the proud community manager of PaperCrowd. We are working hard to improve the services for researchers worldwide.
You should try PaperCrowd - a global directory of academic research conferences. You can search by topics, geography and keywords for research conferences you are interested in such as law, legal etc.
Organizers add their events in a couple of minutes and it’s free. It’s restricted to academic research conferences.
It feels good working for a company that I have seen myself was effective.
