Maven Dependency

The SmartQuery library can be pulled as a maven dependency from our private repository [2].

Essential Usage

The library contains the following three central types:

Simple POJO that represents a single data domain. See the glossary about what a Tenant is.

The central component provided by the SmartQuery library is the QueryMapper. It provides a single and simple method mapQuery.

String mapQuery(String input):
 This method returns a mapped string, if the mapping process was successful and null if not. In such case the input String should be used.

This class is responsible to initialize and manage the QueryMappers for the required Tenants. It needs to be instantiated with the provided API key [3]. It’s necessary to use a single QueryMapperManager object and keep the reference to it, since it will internally spawn and manage several threads to update the QueryMapper instances asynchronously.

QueryMapper getQueryMapper(Tenant t):

The getQueryMapper method will always return the same instance of QueryMapper for the same given Tenant, so it’s not necessary to keep a reference of the QueryMapper. Keeping a reference of a QueryMapper instance isn’t a problem though, since each QueryMapper will be updated in the background.

A non existing tenant won’t cause an error but simply return a QueryMapper that always returns null.

[3]You’ll receive your personal API Key directly from us.

Usage Example

private QueryMapperManager qmManager = new QueryMapperManager("YourApiKey");

public String getSearchQuery(String userQuery)
    Tenant tenant = new Tenant("example", "com");
    QueryMapper qm = qmManager.getQueryMapper(tenant);

    String mappedQuery = qm.mapQuery(userQuery);
    return mappedQuery != null ? mappedQuery : userQuery;
