DCB uses the Zend framework's implementation of the Lucene search engine. This provides a number of options for advanced searching from within the search box. For a full description of the features supported by Zend's Lucene search, see:

• Zend Programmers Reference Guide, chapter 33.4: Zend_search_Lucene > Query language.

What follows is a selection of some of the most commonly used tools.

Phrases

• Use double quotes to search phrases. E.g. search "city hall" to return records containing these two words together in that exact order.

Boolean operators

• Use AND to combine search terms to narrow your search: e.g. search vancouver AND "city hall" to return only descriptions that contain both search terms.

• Use OR to to combine search terms to broaden your search: e.g. search vancouver OR "city hall" to return descriptions that contain either search term.

• Use AND NOT to exclude terms: e.g. search vancouver AND NOT "city hall" to return descriptions that include vancouver but do not contain the phrase "city hall".

• Boolean operators can be upper- or lowercase.

• Other Boolean operators are available; see Zend's documentation.

Fields

• You can restrict your search to specific fields by typing the field name followed by a colon ( : ) and the search text (fieldName:searchText).

• E.g. search title:city to return descriptions which include the word city in the title.

• You must enter the exact field name. These are not always intuitive nor do they necessarily correspond to the field label that appears on screen.

• For the list of searchable fields and their names, see DCB-4.3 Field names for advanced search.
