+* Práctica final
+
+En esta práctica, vamos a implementar un buscar de información en una serie de documentos /JSON/ usando /Apache Lucene/.
+
+** /Parsing/
+
+Parseamos los documentos /JSON/ mediante la librería /GSON/, dado que ésta nos ofrece la posibilidad de serializar el documento en una clase Java.
+
+Esta funcionalidad nos facilita la extracción de información en /JSON/ complejos. Para ellos, creamos la clase *Paper*:
+
+#+begin_src java
+package org.RI.P2;
+
+import java.util.List;
+
+import com.google.gson.annotations.SerializedName;
+
+class Affiliation {
+  String laboratory;
+  String institution;
+}
+
+class Author {
+  String first;
+  List<String> middle;
+  String last;
+  String suffix;
+  Affiliation affiliation;
+  String email;
+}
+
+class Metadata {
+  String title;
+  List<Author> authors;
+}
+
+class Abstract {
+  String text;
+}
+
+public class Paper {
+  String paper_id;
+  Metadata metadata;
+  @SerializedName("abstract") List<Abstract> abstr;
+}
+#+end_src
+
+Es esencial utilizar el mismo nombre de atributo en nuestra clase, dado que esto permitirá un /mapping/ correcto. En caso de que no fuera posible, podemos hacer uso del decorador *@SerializedName*.
+
+El único paso que nos falta es indicarle a la librería la entrada (/JSON/) y la clase.
+
+#+begin_src java
+Gson gson = new Gson();
+Paper data = gson.fromJson(readerJson, Paper.class);
+#+end_src
+
+** Indexación
+
+Para la indexación, hemos elegido los siguientes atributos:
+
+- =paper_id=
+- title
+- authors
+- institution
+- emails
+- abstract
+
+Optamos por crear un índice en cada ejecución, para evitar obtener valores repetidos.
+
+** Buscador
+
+Implementamos un buscador con interfaz gráfica (GUI), basada en el proyecto de ejemplo disponible en la plataforma Prado.
+
+Podemos optar por buscar en diferentes campos, mediante un argumento pasado por línea de comandos. Especificamos las distintas opciones en la sección siguiente.
+
+** Ejecución
+
+En el caso que deseemos utilizar /Maven/, debemos ejecutar los siguientes comandos:
+
+1. Compilar el proyecto
+   
+#+BEGIN_SRC shell
+mvn compile
+#+END_SRC
+
+2. Ejecutar el proyecto
+
+#+BEGIN_SRC shell
+mvn exec:java -Dexec.mainClass="org.RI.P2.Searcher" -Dexec.args="data title"
+#+END_SRC
+
+Debemos modificar el argumento *title* según la salida que deseemos:
+
+- *title*
+- *authors*
+- *abstract*
+- *institutions*
+- *emails*
+
