Full-text search types

The phrase search expression refers to the second argument that you pass to the CONTAINS function call in CBR query. The search expression indicates the type of full-text search to be performed.

There are three main types of full-text searches:

XML An XML search is an XPath-based search of the element and attribute values in XML documents. The following search expression is an example of an XML search:
    @xmlxp:''/zoo/mammal[ .contains("lion")]''
Token A token search is a search for a word or character sequence. For example, if you are searching for the word lion, your search expression can simply consist of the search term lion. Many subtypes and variations of token searches are possible, such as Boolean searches, proximity searches, and fuzzy searches.
Wildcard A wildcard search is special type of token search in which the search term is partially unspecified. In the search term l*n, for example, the asterisk represents unspecified characters. This search term finds any word that begins with the letter l and ends with the letter n.
