only one field for multiples type of resources

about faster searches

[NomikOS]

I have articles, news, faqs, etc.

If I use only one field for store theirs body contents, obviously I can offer speedy searches, right?

Is there any con with that? someone do it?

TIA, NomikOS

Will people always want to search everything on the site, or might they usually want to search articles and FAQs seperately?
