131294 All Keywords for root keywords

Hi, I have 1098 Niche Phrases, and keywords. The project is to find all the keywords people search for each keyword. For example one of the keywords is "Erection" I would need all the keywords for that word like: "strong erection" / "rock hard erection" + seach per month. I must have all this info from the overture database, if you have more sources, you are more than welcome to use them Remember, there are about 1090 keywords (phrases) Part 2: You muct filter keywords that are not relevant to a "sexual enhancer' product. Thanks
