Defining Queries

Given these example indexers, it is straightforward to define queries, just use the self-explanatory API.

This query searches for persons called 'John', firstName is a static imported field from the class where we defined our indices before.

gigaMap.query(firstName.is("John"));

Conditions can be linked with and and or, respectively.

This one searches for all persons called 'John' or 'Jim'.

gigaMap.query(firstName.is("John").or(firstName.is("Jim")));

Or use the in condition instead.

gigaMap.query(firstName.in("John", "Jim"));

It is possible to compare to fixed values, but we can also use predicates. This enables us to use any custom logic inside query definitions if the predefined ones are not sufficient.

gigaMap.query(firstName.is(name -> name.length() > 3));
