Key message corresponding to generic attribute changed obtained by value；
It should be noted that every kind of classification category can be prestored in embodiments of the present invention, in Key-Value databases
Concordance list corresponding to property；Each concordance list includes：Key, reference value in Key-Value databases, and Key and reference value
Corresponding relation.Wherein reference value is to use the default conversion regime, and the key message corresponding to categorical attribute is turned
Change acquisition.
With reference to table one and table two, the target concordance list in this programme is illustrated.
Referring to table one, table one is the target concordance list corresponding to name categorical attribute, i.e. name concordance list：
Table one
Wherein, being recorded in name concordance list has：Reference value 100 corresponding to name " Zhang San " corresponding to student number 1, student number 1, with
And student number 1 and the corresponding relation of reference value 100；Reference value 200 corresponding to name " Li Si " corresponding to student number 2, student number 2, and
Student number 2 and the corresponding relation of reference value 200 etc..Wherein, student number Key；The reference value 100 is according to default conversion side
Formula, carry out what numerical value was converted to " Zhang San "；The reference value 200 is according to default conversion regime, enters line number to " Li Si "
What value was converted to, and the default conversion regime of reference value conversion is carried out to name categorical attribute, referred to above-mentioned steps S102
To name categorical attribute carry out target reference conversion default conversion regime it is identical.
When requiring to look up the information of people that name in Key-Value databases is Zhang San, determine that target critical information is
Zhang San, and the target classification attribute corresponding to Zhang San is name；According to default conversion regime, Zhang San is converted into object reference
Value 100；Name concordance list is searched using target reference 100.
Referring to table two, table two is the target concordance list corresponding to character classification by age attribute, i.e. age concordance list：
Table two
Wherein, in age concordance list there is record：Reference value 26 corresponding to age " 26 " corresponding to student number 1, student number 1, and
The corresponding relation of student number 1 and reference value 26；Reference value 26 corresponding to age " 26 " corresponding to student number 2, student number 2, and the He of student number 2
Corresponding relation of reference value 26 etc..Wherein, student number Key；The reference value 26 is according to default conversion regime, and " 26 " are entered
Line number value is converted to, and this carries out the default conversion regime of reference value conversion to character classification by age attribute, with above-mentioned steps
The default conversion regime that reference value conversion is carried out to character classification by age attribute that S102 is referred to is identical.

Value values corresponding to being searched in database, as search result.So when search condition is Value content, it can improve
Search efficiency.
Target critical information and target classification attribute are further described below.
For example, when the search condition of user is：The Value daily record generation time is in search Key-Value databases
During the daily record of " 20160507 ", then " 20160507 " can be defined as to target critical information, the daily record generation time is defined as institute
State the target classification attribute corresponding to " 20160507 ".When the search condition of user is：Search in Key-Value databases
When Value log content is the daily record of " deletion client ", log content " deletion client " is defined as target critical letter
Breath, log content are defined as target classification attribute corresponding to " the deletion client ".
It is understood that the example above is merely illustrative, should not form to target critical information and target classification attribute
Restriction.
With reference to above-mentioned to target critical information and the specific example of target classification attribute, to target critical information is converted to
The default conversion regime of target reference illustrates.
For example, when target critical information is date " 20160507 ", i.e., when target critical information is pure digi-tal, preset
Conversion regime can be：Target critical information is continued to use, then the target reference corresponding to target critical information 20160507 is
20160507.Certainly presetting conversion regime can also be：A millisecond number is converted into by 20160507, then target critical information
Target reference corresponding to 20160507 is 1462593600000.Wherein, it is existing skill to be converted into millisecond number by 20160507
Art, specific conversion method is not described in detail herein.
, can be according to corresponding to default " deletion client " when target critical information is defined as " deletion client "
Numeral, such as 1101, then the deletion client is converted into target reference 1101.Key message corresponding to every kind of categorical attribute
Corresponding reference value, it can pre-set and preserve.
It is understood that the example above is merely illustrative, it is not the specific restriction to presetting conversion regime.
It is understood that as a kind of embodiment, can it is determined that the target critical information that search condition includes, and
Before target classification attribute corresponding to the target critical information, target concordance list corresponding to the target classification attribute is built.I.e.
Structure obtains target concordance list in advance, when performing search operation, the target concordance list need to be only called, improve search
Speed.
As another embodiment, institute can also searched in the target concordance list corresponding to the target classification attribute
Before stating the target Key corresponding to target reference, the operation of structure target concordance list is performed.So that constructed target index
Table is newest concordance list, improves the search degree of accuracy.
The step of below to building target concordance list corresponding to the target classification attribute, illustrates, as shown in Fig. 2 structure
The target concordance list is built to may include steps of：
S1：Obtain multiple Key in Key-Value databases；
Wherein, when needing to build target concordance list corresponding to the Key-Value databases, it is necessary to described in first obtaining
Multiple Key included in Key-Value databases.
For example, it is assumed that N bar daily records, the corresponding Key of every daily record are included in Key-Value databases.Work as needs
It is, it is necessary to first obtain corresponding to the N bar daily records when daily record generates the target concordance list corresponding to the time to build target classification attribute
Key.Wherein, Key corresponding to every daily record being capable of unique mark this daily record.
S2：Obtain Value corresponding to each Key；
Wherein it is possible to according to the Key of acquisition, Value contents corresponding to the Key are found.N number of Key be present for example, working as
When, then corresponding N bars Value contents can be found, this is prior art, and it is not described here in detail.
S3：Institute in the Value according to corresponding to Value corresponding to each Key determines the first Key and the first Key
State the first key message corresponding to target classification attribute；First Key is that the Key-Value databases include the mesh
Mark Key corresponding to the Value of key message corresponding to categorical attribute；
After the Value contents corresponding to each Key are obtained, target classification attribute described in every Value content is searched
Corresponding key message.Value contents are included into Key corresponding to the Value of key message corresponding to target classification attribute,
It is defined as the first Key；By key message corresponding to target classification attribute is defined as first described in Value corresponding to the first Key
Key message.
For example, N bar daily records, the corresponding Key of every daily record are stored with Key-Value databases.It is such as a certain
It is 20160101 that the daily record generation time is stored with bar daily record, the information such as log content " deletion client ", and this daily record pair
The Key1 answered is the journal number of this daily record.After it is determined that target classification attribute is log content, it is Sino-Japan to obtain this daily record
First key message corresponding to will content, that is, the first key message is obtained to delete client.
S4：According to the default conversion regime, first key message is converted into the first reference value；
Wherein, according to default conversion regime, the first key message of Value corresponding to each first Key is converted to
One reference value.Such as by above-mentioned first key message " deletion client ", it is corresponding according to the deletion client set in advance
Transforming numerical, switched to the first reference value 1101.
S5：Target concordance list corresponding to the target classification attribute is generated, wherein, record has the in the target concordance list
One Key and the first reference value corresponding relation.
For above-mentioned example, generate the target classification attribute corresponding to target concordance list, refer to generate in the daily record
Log content concordance list corresponding to appearance.Record has journal number with the first ginseng corresponding to log content in the log content concordance list
Examine the corresponding relation between value.
It should be noted that the structure to target concordance list can be realized by above-mentioned S1-S5, certain structure flow
It is merely exemplary, it should not form the restriction of the sequencing to building target concordance list.
Alternatively, the corresponding relation in the target concordance list generated is deposited according to reference value ascending order mode or descending mode
Storage.
It is understood that because search procedure needs to be matched using target concordance list, therefore in order to improve matching
Speed, according to reference value ascending order mode or descending mode, the corresponding relation in target concordance list is stored.This kind of sequence side
Formula, while being ranked up according to reference value progress ascending order mode or descending mode, the Key corresponding to reference numeral is also entered
Sequence is gone.
For example, Key-Value databases include N bar daily records, the Key of every daily record is journal number.Journal number is 1
Log content is " deletion client ", and according to default conversion regime, " deletion client " is converted into reference value 12345678；Compile
Number log content for being 2 is " modification client ", and according to default conversion regime, " modification client " is converted into reference value
12345679；……；The keyword for the daily record that numbering is N is " detection client ", will " detection visitor according to default conversion regime
Family end " is converted to reference value 123xxxxx.Wherein, the bigger corresponding reference value of number value is bigger.
Therefore the ascending sort established based on reference value to corresponding relation is：1(12345678)→2(12345679)
→……→N(123xxxxx)。
It is understood that Key-Value databases, such as Redis databases, can be by way of sorted set
Store above-mentioned sequencing information.Wherein sorted set mode is prior art, this kind of storage mode is not done specifically retouched herein
State.
