Building a Vector Space Search Engine in Python
A vector space search involves converting documents into vectors. Each dimension within the vectors represents a term. If a document contains that term then the value within the vector is greater
than zero.

Mix prices?
Good day!
So, I'll try to make this short and simple....
1. Got a mix gig and they loved the mix, I only charged $50 for it and we didn't sign many papers =( ((i know..))
2. Have had many professionals tell me that my mix is worth $150 at least
3.
