Source is traveled through, and the second traversing result that will generate after traversal returns client-side search session, client-side search session cache the
One traversing result and the second traversing result simultaneously merge；If changing, server search session is fixed by the first traversing result
Amount returns client, client-side search session cache first traversing result；
Step S303, client and server create new search sessions, and server again travels through all according to new search condition
Data source.
When being embodied as, because server is only once traveled through to data source, so the condition of user input must be
Meet necessarily rule, be such as unsatisfactory for rule condition then need to re-create new search sessions, new search sessions will again
Begin stepping through data source.
Same session scenario: a->ab->abc->abcd->ab->a->abcd
abc->abcd->ab->a
Non- same session scenario:a->ab->a->Ac (now using new search session).
It is search sessions after input condition character first, be same session when successive character is incremented by one by one, if after
Precondition does not have inclusion relation (if previous condition is ab, New Terms is ac), then this conversation end to continuous condition therewith, uses
New session scans for, and has not only provided good operability but also has improved search efficiency, has reduced the stand-by period of user.
In further embodiment, step S302 specifically includes：
The first traversing result that step S321, client-side search session waiting for server search sessions return, and first is traveled through
Result initial ranging condition corresponding with the first traversing result enters row cache；

Family end search sessions carry out local filter to the first traversing result of caching immediately, and notify server search session；
First traversing result of current traversal is returned client-side search session by step S323, server search session immediately, and
Not traversed data source is traveled through using new search condition by server search session, second generating after traversal
Traversing result returns client-side search session；
Step S324, client-side search session cache second traversing result, and merge life with the first traversing result prestoring
Become final traversing result, final traversing result is back to UI interface.
When being embodied as, if when new search condition and initial ranging conditional server iterations when condition does not change
Reach specified quantity (quantity can configure) and then notify a client search results (fruiting quantities >=0), if condition change, stand
Notify client search results, after notifying client, continue traversal following resource using New Terms, until traversal completes.
After client-side search session initiation, then waiting for server notifies Search Results, and each Search Results and this time are searched
The corresponding condition of hitch fruit is cached, if receiving result for the first time, immediately this result being returned to UI and presenting.Work as condition
During change, immediately local filter is carried out to the result of caching, notify the change of server search session condition simultaneously.Work as server
After subsequent notification Search Results, client should cache this result and merge before result, then this result returned to UI be in
It is existing.
Because server only needs once to be traveled through, therefore greatly reduce the pressure of server and decrease calculation times, visitor
Family end carries out binary search to local data during server search simultaneously, has reached quick with server concurrent processing

Again all data sources are traveled through.
10. the system of fast search according to claim 9 is it is characterised in that described traversing result acquiring unit is also wrapped
Include：
Traversing result buffer unit, the first traversing result returning for client-side search session waiting for server search sessions,
And corresponding with the first traversing result for the first traversing result initial ranging condition is entered row cache；
Data filtering units, for becoming compared with initial ranging condition when client-side search session detects new search condition
When more, client-side search session carries out local filter to the first traversing result of caching immediately, and notifies server search meeting
Words；
First traversing result of current traversal is returned client for server search session by the second data traversal unit immediately
Search sessions, and not traversed data source is traveled through using new search condition by server search session, will travel through
The second traversing result generating afterwards returns client-side search session；
Traversing result combining unit, for client-side search session cache second traversing result, and with the first pass prestoring
Go through result and merge the final traversing result of generation, final traversing result is back to UI interface.
