Hi all,

I'm creating an app with articles and tags, its there an easy way to find all the articles with specific tags easily?

e.g.

Article 1 has x,y,z
Article 2 has a,b,c
Article 3 has x,z
Article 4 has x
Article 5 has x,z

I want find all the articles with x and z easily or all with z, in reusable way.

I may want to look for 3 or 1 tag, at the moment I'm doing it in PHP as I dont want SQL statement per number of tags I'm lookin for

Thanks for any help
