Show to user.In embodiments of the present invention, data are not limited in the specific storage mode on backstage, for example, data can store
In the database, it also can store in file system (including local file system and distributed file system).
In data retrieval method provided in an embodiment of the present invention, need using index classification configuration, index configurations, index
Strategy configuration and data object configuration totally four kinds of configurations, wherein have recorded index item name in index classification configuration, index
Index is had recorded in configuration and indexes the incidence relation (there can be one or more indexes under an index classification) of classification, index
The incidence relation (there can be one or more data objects under an index) of index and data object is had recorded in strategy configuration,
Having recorded data object and the incidence relation of attribute in data object configuration (can have one or more categories under a data object
Property).
In one embodiment, contents of these configurations can be with are as follows:
Index classification configuration: index item name；
Index configurations: index name, index item name；
Index strategy configuration: index policy name, index name, data object title；
Data object configuration: object oriented, Property Name.
Above-mentioned configuration can be implemented as the table in database, also can be implemented as configuring in some implementations certainly
The forms such as file illustrate to simplify below, might as well assume that these configuration informations are stored in the database on backstage, but this
Kind is assumed to be not to be construed as limiting the scope of the invention.
Data object may include initial data and object oriented, be a kind of abstract representation to initial data, and attribute is
Description to certain features of initial data, or it is considered as the customized label added for initial data, usual attribute is answered
It is defined when according to specific Search Requirement.Index is a kind of data structure, for accelerating the retrieval rate to data.Index
Classification is for classifying to index, and since data are always by index accesses, indexing classification simultaneously is also to data
Classification.
Above-mentioned concept is exemplified below.Assuming that there is the file of a 1.MP4 to be retrieved, it can be in data object
Increase a record in configuration, object oriented is " file ", object properties entitled " extension name " and " file size ", in rope
Draw and also increase a record in classification configuration, index item name is " video ", also increases a record, rope in index configurations
Drawing entitled " MP4 video file ", also increases a record in index strategy configuration, index name is " MP4 video file ",
Object oriented is " file ".In this way, just completing the foundation for the 1.MP4 configuration information retrieved.
These configuration informations can be edited on the interface of front end by user, store in the database, need after editor
It is read from database when using.It certainly, can be in data in retrieval in order to accelerate the access speed for these configurations
These configurations are loaded into caching by searching system when starting, subsequent to be directly read out from caching in retrieval.
It should be understood that these configuration can front end by user change, including to configuration item increase, delete or
Person's modification.Backstage response user updates corresponding configuration item in the configuration modification operation of front end made in the database.If
Configuration information is already loaded into caching, then the content in caching needs synchronously to modify, and avoids the occurrence of the inconsistency of data.
It currently assumes and has been stored with data in data retrieval system, and and retrieve relevant index classification configuration, index
Configuration, the configuration of index strategy and data object configuration are configured good.Referring to Fig. 2, data retrieval method is specifically included:
Step S10: retrieval content and index classification are obtained from front end.
Retrieval content is inputted in front-end interface by user, and is sent to backstage, while user should also in retrieval
Assigned indexes classification.Wherein, specified index classification should be defined in index classification configuration.
Step S11: at least one index obtained with index category associations is searched.
The incidence relation of index classification and index records in index configurations, but should be noted that and remember in index configurations
The only description to incidence relation of record really indexes bottom of the classification with index in data retrieval system and be associated with depositing
Storage indexes classification by available arrive that record in index configurations, and then gets the index being associated.
Step S12: it searches and obtains and index at least one associated data object.
It indexes and is recorded in index configurations with the incidence relation of data object, but should be noted that index strategy configuration
The only description to incidence relation of middle record, really index and data object are closed in the bottom of data retrieval system
Join and store, is indexed by available arrive that record in index strategy configuration, and then get the data object being associated.
Step S13: it searches and obtains and at least one associated attribute of data object.
The incidence relation of data object and attribute records in data object configuration, but should be noted that data object
The only description to incidence relation recorded in configuration, real data object and attribute are carried out in the bottom of data retrieval system
Associated storage, by data object configure in record available to data object, and then get the category being associated
Property.
Step S14: judge at least one attribute with the presence or absence of the attribute to match with retrieval content.
Matching in step S14, which refers to, meets search condition, for example, it may be it is equal, comprising etc. conditions.According to retrieval
The difference of content, step S14 can be retrieved in each attribute, are also possible to combine multiple attributes while be examined
Rope.It should be pointed out that the retrieval in the embodiment of the present invention only carries out in attribute, and no longer carried out in data itself, therefore
Attribute needs appropriate definition, is allowed to the demand of retrieval be adaptable
Step S15: the attribute to match if it exists determines that data object is matched data object and by matched data object
It is back to front end displaying.
In one implementation, as soon as front-end interface displaying is returned it to after can building and retrieving matching object,
Realize the real-time exhibition of search result.It in another embodiment, can also be after retrieving a matched data object first
It being cached, continuation is retrieved in other data objects, until retrieval finishes, all coupling numbers that then will be retrieved
Front-end interface is back to simultaneously according to object to show.
It should be understood that can also show other information, such as matched data simultaneously other than display data object
The attribute of object to match or with the associated whole attributes of matched data object.
By taking the example of the 1.MP4 mentioned before as an example, it is assumed that the retrieval content that user inputs in data retrieval system is
" MP4 ", search condition is equal, while specified index classification is " video ", and backstage is looked into according to index classification " video " first
Index " MP4 video file " is found, data object " file ", data object are then found according to index " MP4 video file "
" file " is exactly file 1.MP4 in the particular content that bottom stores, and then finds attribute " extension according to data object " file "
Name " and " file size ", attribute " extension name " are exactly " MP4 " in the particular content that bottom stores, therefore in the attribute and retrieval
Appearance be it is matched, the corresponding data object of file 1.MP4 is back to front end and is shown, at the same can also show its " extension name " and
" file size ".
Above-mentioned data retrieval method carries out the definition of objectification in data object configuration to data to be retrieved, and is arranged
The hope of data object is used for the attribute retrieved.Wherein, attribute can be regarded as the label of data object, in these labels
In retrieved, efficiency far is higher than to be retrieved in all data in the prior art, therefore can be realized efficient number
According to retrieval.Simultaneously as attribute can data object configuration in customized setting, freedom degree is very high, therefore can prop up
It holds and various dimensions, many condition retrieval is carried out to data.Quite data have been carried out centainly in addition, classification is indexed and indexed by setting
Classification in degree had both improved the efficiency of data retrieval, is also convenient for user and carries out Classification Management to data.
It in one embodiment of the invention, can be by executing step S20 to step S23 before step S10 execution
The storing data into data retrieval system retrieves these data so as to subsequent.Referring to Fig. 3:
Step S20: after data memory interface is called, obtain the data object incoming as call parameters and with number
According at least one associated attribute of object.
Backstage externally provides data memory interface, which can be called by foreground or other third party systems, be used for
Data are stored into data retrieval system.Note that storage mentioned here refers to that data are in the management of data retrieval system
Under, as data retrieval system bottom how storing data, be not construed as limiting.
The parameter of data memory interface includes data object and wishes and the associated attribute of data object, wherein data
Object also may further include two parameters, the i.e. object oriented of the initial data of data object and data object.
Step S21: by data object and at least one attribute according to data object configure in relationship store.
Firstly, data object has to be stored, meanwhile, in order to find attribute by data object, need by
Data object and attribute actual association, the associated storage in step S21, refer to carried out in the bottom of data retrieval system it is true
Associated storage.
Step S22: the corresponding index of data object is obtained from indexing to search in strategy configuration, and by data object and is indexed
According to the relationship storage in index strategy configuration.
After data object is stored, in order to retrieve data object by index, need to index and number
According to object actual association.Associated storage in step S22 also refers to really be associated in the bottom of data retrieval system
Storage.
Index can just be automatically generated when carrying out the configuration of configuration information, but index at this time is empty index, and is not related to
Join any data object, establishes and be associated with index during data object is stored, while index data is updated.
Step S23: searching from index configurations and obtain the corresponding index classification of index, and will index and index classification according to
Relationship storage in index configurations.
