The Results Order
The results order based on the id() number in class PageText, descending order.
A Page has many PageTexts. if don't need multiple Texts, modify Html.getDefaultTexts(Page), returns only one PageText.
the Page.GetRandomContent() method is used to keep the Search-Page-Content always changing, doesn't affect the real PageText order.
Use the ID number to control the order instead of loading all pages to memory. Or load top 100 pages to memory then re-order it by favor.
search (... String keywords, long startId, long count)
startId => which ID(the id when you created PageText) to start, use (startId=Long.MaxValue) to read from the top, descending order
count => records to read, important parameter, the search speed depends on this parameter, not how big the data is.
set the startId as the last id from the results of search minus one
startId = search( "keywords", startId, count); nextpage_startId = startId - 1 // this 'minus one' has done inside search() ... //read next page search("keywords", nextpage_startId, count)
public Page Html.Get(String url);
Set your private WebSite text
Page page = new Page(); page.url = url; page.title = title; page.text = bodyText page... = ... return page;
