4, search monogram " aq " and be present in the program that the programm name initial makes up the 2nd; Retrieve 3 programs, " asking love ", " heavily like light friend ", " love is carried through to the end " add the result for retrieval in the 1st step; Retrieve 6 programs altogether, changeed for the 5th step;
5, show all programs that retrieve in the 1st step and the 2nd step.
If the user does not still find the program of wanting in this page, click again " following one page ", system then searches downwards in database:
6, continue in database, to search monogram " aq " and be present in the program that the programm name initial makes up the 2nd, result for retrieval is 0, and so far, system is present in the situation retrieval that the program initial makes up the 2nd with the key letter combination and finishes, and changes for the 7th step;
7, search monogram " aq " and be present in the program that the programm name initial makes up the 3rd; Result for retrieval is 2; " perfect love ", " believing love ", so far, system is present in the situation retrieval that the program initial makes up the 3rd with key letter combination and finishes; The not enough demonstration, changeed for the 8th step;
8, search monogram " aq " and be present in the program that the programm name initial makes up the 4th; Result for retrieval is 3, " one love in all one's life ", " not removing to like money ", " dear A Qing ", so far; System is present in the situation retrieval that the program initial makes up the 4th with key letter combination and finishes; And the program that whole satisfied retrieval requires also travels through and finishes, and total result for retrieval is 5, changes for the 9th step;
9, show all result for retrieval in the 2nd step, the 3rd step and the 4th step.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
