adult search engine - repost

looking to buiiild a porn search engine for free tube sites such as [login to view URL], [login to view URL], etc... Process we desire: 1. users enters search query terms 2. search query terms are sent to scaper (scrapy) using AJAX call 3.. scraper forwards search query to top sites in url list 4. scraper retreives 10 pages of responses or max number of responses (which ever comes first) from each site 5. search results (thumbnails, video links) are stored in MySQL database and reference by a query -ID and the search query terms. page numbers are also assigned 20 results /page 6. results are retreived from each of the target sites so that the results set doesnt appear to have any site in particular 7. the results are gathered via ajaz, are desplayed as rows/colonms of thumbnails. the first set of results are available via (page...?) at the bottom of the page. (Page...?) levels access the database results via the search query ID and page number using a PhP script 8. the front end user (twitter bootstrap) to deploy 9 (twitter bootstrap uses ajax to talk to the middle tier which is in PhP and Scrapy 10. user clicks on video, video opens on OUR video site. video pulled using iframes and embed code. we cannot host video. ** will probably need to build database for search into to pull results. this will speed up query. Search will consist of 12-15 free tube sites. Results: Sort by: length, date, source Web site: twitter bootstrap for home(search) and results page. designs already compete.
