Class BooleanQuery

java.lang.Object

com.atlassian.confluence.search.v2.query.BooleanQuery

All Implemented Interfaces:

Expandable<SearchQuery>, SearchQuery

@SearchPrimitive
public class BooleanQuery
extends Object
implements SearchQuery

A boolean query that allows and/or and not combinations of sub queries.

TODO: This SearchQuery implementation does not work with the QuerySerializer (or parser) since that mechanism relies on all parameters returned by getParameters having the same meaning; this is not currently true in this implementation.

BooleanQuery

                    Collection<? extends SearchQuery> should,
                    Collection<? extends SearchQuery> mustNot)

Construct a new BooleanQuery encapsulating the supplied sub queries. At least one of must, should or mustNot subquery must contain value.

Parameters:

must - the queries that must match.

should - the queries that may match.

mustNot - the queries that must not match.

Throws:

IllegalArgumentException - if the parameters are not correct.

                    Collection<? extends SearchQuery> mustNot,
                    float boost)

Construct a new BooleanQuery encapsulating the supplied sub queries. At least one of must, should or mustNot subquery must contain value.

Parameters:

must - the queries that must match.

should - the queries that may match.

mustNot - the queries that must not match.

boost - the boost factor.

Throws:

IllegalArgumentException - if the parameters are not correct.

Method Detail

getKey

public String getKey()

Specified by:

getKey in interface SearchQuery

Returns:

the plugin key

composeAndQuery

public static SearchQuery composeAndQuery(Set<? extends SearchQuery> subqueries)

Return a query that "ANDs" together a list of queries. If the list contains no entries then an AllQuery is installed. If it contains only a single entry, then that entry is returned. Otherwise a BooleanQuery combining the full list is returned.

Parameters:

subqueries - a list of SearchQuerys to combine. Must have size >= 1.

Returns:

a SearchQuery combining the subqueries.

Throws:

IllegalArgumentException - if the list of subqueries is empty.

andQuery

public static SearchQuery andQuery(SearchQuery... queries)

Build an AND query from one or more subqueries.

Parameters:

queries - the SearchQuerys to combine. Must be >= 1.

Returns:

a SearchQuery combining the subqueries.

Throws:

IllegalArgumentException - if the list of subqueries is empty.

composeOrQuery

public static SearchQuery composeOrQuery(Set<? extends SearchQuery> subqueries)

Return a query that "ORs" together a list of queries. If the list contains no entries then an AllQuery is installed. If it contains only a single entry, then that entry is returned. Otherwise a BooleanQuery combining the full list is returned.

Parameters:

subqueries - a list of SearchQuerys to combine. Must have size >= 1.

Returns:

a SearchQuery combining the subqueries.

Throws:

IllegalArgumentException - if the list of subqueries is empty.

orQuery

public static SearchQuery orQuery(SearchQuery... queries)

Create a query that is the OR of the provided sub-queries

Parameters:

queries - the queries to OR

Returns:

the OR of the provided queries

getMustQueries

public Set<SearchQuery> getMustQueries()

getShouldQueries

public Set<SearchQuery> getShouldQueries()

getMustNotQueries

public Set<SearchQuery> getMustNotQueries()

expand

public SearchQuery expand()

Description copied from interface: SearchQuery

Expands this query into a composite query (that composes other queries). By overriding this method, one can specify a new query that is composition of the behaviour of the composed queries.

Specified by:

expand in interface Expandable<SearchQuery>

Specified by:

expand in interface SearchQuery

Returns:

a query

getParameters

public List getParameters()

Description copied from interface: SearchQuery

List of parameters as Strings or SearchQuerys.

Specified by:

getParameters in interface SearchQuery

Returns:

a List containing all the sub queries combined together. I'm not sure this is ever useful to anyone.

getBoost

public float getBoost()

Description copied from interface: SearchQuery

Return boost factor of this query. It will take effect when the query is used in combination with others e.g. in BooleanQuery.

Specified by:

getBoost in interface SearchQuery

Returns:

boost factor

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

builder

public static BooleanQuery.Builder builder()
