I have actually pretty simple question. Having new sitemap every week and get it indexed immediately. How can I guarantee that the new fresh content will be indexed immediately by Google without building new sitemap. I suspect there are should be kind of trigger to index just one particular URL that will be working with huge sitemap created early.
your fresh content on Google
seo;google search;indexing;xml sitemap
There is no way to guarantee it. Google will crawl your site whenever it feels like it. Typically sites that are updated often and have a lot of quality links are crawled more frequently then those that do not. UpdateIn response to your comments: Your sitemap should reflect all of the content on your website that you wish to have crawled and indexed. So if you keep adding pages to your site then your sitemap should grow accordingly. Like I said in my answer above, Google isn't going to find your changes or update its index quickly for a site like yours. You need to be patient and continue to add content and seek links to your site. Google will eventually find your changes and update its index accordingly. If and when this happens is beyond your direct control.
