Can I use my sharepoint library like the original wikipedia?

i'm not very experienced with sharepoint at all, so this might be a silly question. but here's what i would like to do.

i would like to create my own thematic wikipedia using a sharepoint library wiki. is this possible in principle? if the answer is yes - how do i do it? i'd like to create a main page including a search bar. inserting a search item should lead to an extra page explaining the item - just like we are all used to it from wikipedia.

i'd really appreciate any help. thanks in advance!

p.s.: i'd also appreciate a link to a good sharepoint documentation.
