HIVE Core

vocabulary.properties

A new autocomplete property has been added to the vocabulary.properties file. This property specifies the path to the directory that will contain the autocomplete index.

AdminVocabularies

A new flag -x has been added to the AdminVocabularies class to support initialization of the autocomplete index:

java edu.unc.ils.mrc.hive.admin.AdminVocabularies -c <path-to-conf-dir> -v <vocabulary> -x

Specifying this flag will create the autocomplete index.

Autocomplete class

A new class edu.unc.ils.mrc.hive.ir.lucene.search.Autocomplete has been added to the hive-core.jar. This class handles the initialization of the autocomplete Lucene index and term suggestion (search).

HIVE Web

Autocomplete Servlet

A new servlet org.unc.hive.servlet.AutocompleteServlet has been added to the hiveweb web application. This servlet accepts two parameters cv and term and returns a JSON-based response with suggested terms.

Autocomplete Widget

A simple JQuery-based autocomplete widget has been added to the project to demonstrate one possible integration approach.
