Data query method disclosed by the invention can be applied in view networking, depending on may include terminal and backstage in networking
Server, terminal and background server communication connection.Data query method disclosed by the invention is a kind of associative search mode,
It goes to match corresponding result set according to certain atom collection.In data source, for wanting to obtain target value, from search key
Minimum cargo tracer place value starts, and obtains result set, and on the basis of the result set that upper primary inquiry obtains, successively inverted order is passed
Increase Query Value to scan for, gradually simplify query results, final reverse screening obtains target value.
It is a kind of step flow chart of data query method of the embodiment of the present invention with reference to Fig. 5, the method may include
Following steps:
Step S501 receives the search key that the terminal is sent.
Step S502 is decomposed to obtain the first Query Value for described search keyword, wherein first Query Value
For the minimum unit value of described search keyword.
Search key can be user and be input to terminal, and terminal is then forwarded to background server.Background server exists
After receiving search key, search key is decomposed, then extracts the first Query Value.The magnitude of first Query Value is
The minimum unit value of search key.For example, the search key of user's input is " video conference ", then background server is to searching
Rope keyword is decomposed, and respectively obtains view, frequency, meeting, the Query Value for discussing 4 minimum unit values, then one of them is as the
One Query Value.When background server scans in data source according to the first Query Value, with the first inquiry of minimum unit value
Matching is compared in value, and required calculation amount is smaller, can effectively promote the speed of data search.
Step S503 scans for obtaining the first result set according to first Query Value, and by first result set
It is sent to the terminal, so that the first result set described in the terminal display.
In data source, scanned for obtaining the first result set in data source according to the first Query Value.For example, search is closed
Keyword is " video conference ", and server extracts " depending on " as the first Query Value, according to " depending on " after being decomposed " video conference "
Scan in data source, may include in the first result set searched for: so-and-so video, so-and-so videograph, so-and-so
Video conference, video, video conference record, video conferencing record, video conference etc. include the result of " depending on " word.
It is scanned for according to the minimum unit value of search key, can search for obtain comprising more relevant search contents
Result set, for example, above-mentioned video conferencing records.And the first result set that search obtains is sent to terminal, passes through terminal
Search result more abundant is showed into user, promotes the usage experience of user.
Step S504, receive that the terminal sends continues searching request, wherein described to continue searching request be the end
When end does not obtain search target according to first result set judgement, what Xiang Suoshu background server was sent.
Terminal judges search target whether is obtained in the first result set after showing the first result set, and is not obtaining
Request is continued searching to background server transmission to when searching for target.
It should be noted that can judge whether obtain search target in the first result set using various ways.One
In kind judgment mode, the operation of active user can be intended to continue searching request to determine whether sending by terminal, for example,
If user ceaselessly stirs, browser interface, do not stopped in some page but, terminal can think user the of current presentation
It does not search to obtain search target in one result set, continues searching request to background server transmission.In another judgment mode,
It can also decide whether to send depending on the user's operation and continue searching request, for example, if the first knot that user shows in browsing
It when the first page of fruit collection, just wants to continue searching for, button can be continued searching by clicking, send out terminal to background server
It send and continues searching request.
Outside divided by upper type, the judgement of terminal and the operation of user can also be combined, to decide whether to take to backstage
Business device transmission continues searching request, continues for example, terminal can be sent in the case where meeting the following conditions to background server
Searching request:
1, user sends after browser interface preset time and continues searching request, and preset time can be set according to demand,
For example, any time in 15-20S.
2, whether terminal recognition current presentation interface jumps.If the interface of current presentation is jumped, i.e., it is believed that
User is interested in some search result in the first result set, at this point, not continuing searching request to background server transmission.
3, background server judgement is preferential, subject to user's operation.When background server is judged to need to continue searching, to
User interface sends the click interface for whether continuing searching request, only in the case where user agrees to send and continues searching request,
Just request is continued searching to background server transmission.
In this embodiment, it is preferred that the third above-mentioned mode can be used, i.e., backstage judges preferential that user's operation is
Standard can effectively promote the usage experience of user.
Step S505, judges whether the first result in first result set is greater than pre-set level.
Step S506 carries out described search keyword in the case where first result is greater than the pre-set level
Decomposition obtains the second Query Value, wherein the unit value of second Query Value is greater than the unit value of first Query Value.
Specifically, background server judges the first result in the first result set after receiving and continuing searching request
