com.attivio.sdk.search.query.Query

com.attivio.sdk.search.query.QueryString

All Implemented Interfaces:

QueryParameters, LocaleAware, Serializable, Cloneable

public final class QueryString
extends Query

Query operator that contains an unparsed query string.

This query object can specify the query language to use to parse the attached query string. Out of the box support is present for the Attivio advanced (QueryLanguages.ADVANCED and simple (QueryLanguages.SIMPLE) query languages.

NOTE: This is not a concrete query implementation. The contained query string must be parsed and replace this QueryString in the query tree in order to be interpreted properly.
