Nope, if you meant the spider not that exactly, I'll try to explain further.
Lets say you have links running with 20 links; www.a.com (sells the product a), www.b.com (sells the product b) etc. Someone searching for product "a" obviously finds the first link and any other link that mentions the product "a" in their description and keywords. What I'm looking for is if someone searches for the product "z" although the product is not mentioned in any description or keywords it may be mentioned somewhere on the site of www.a.com or any other of the links pages; so is there someway of spidering and recording the full text on the links pages (on say a monthly basis) so someone searching can come up with with a "z" result.
