com.lucidworks.search.dsl.request.query.QueryDefinition

public class QueryDefinition
extends DslCloneable

A container object for all queries in DSL request. There are following assumptions between getUserQuery() and getMain():

If getUserQuery() is set and getMain() is not, getMain() will be set to TextQuery with getUserQuery() as a value.

If getUserQuery() is set and getMain() is set, assumption is that getMain() query contains some TextQuery(s) without a value which will default to getUserQuery() as a value.

Expectation is for at least one of getUserQuery() and getMain() fields to be populated

getGroupedQuery() and getGroupedFilters() are used in relation with Results.getGroup(). Expectation is for Results.getGroup() to be set if any of these queries are set.

Note: keep in mind that not all of the queries that could be specified in DslRequest located here. Some are specific to a particular part of request and located there (for example "sort by" queries)

QueryDefinition

                       List<BoostQuery> boostsByQuery,

Method Detail

getMain

public Query getMain()

Returns:

main query that defines the base result set and document scores for this request. If null, defaults to TextQuery with getUserQuery() value

setMain

public void setMain(Query main)

getBoostsByValues

public List<BoostByValue> getBoostsByValues()

Returns:

a list of fields and boost values that will be used in combination with getBoostsByQuery() and will be added to getMain() to influence the score. Boosts by query and value have no impact on the result set.

getBoostsByQuery

public List<BoostQuery> getBoostsByQuery()

Returns:

a list of additional queries that that will be used in combination with getBoostsByValues() and will be added to getMain() to influence the score. Boosts by query and value have no impact on the result set.

getUserQuery

public String getUserQuery()

Returns:

actual user query that is used in combination with getMain()

getFilters

public List<Query> getFilters()

Returns:

a list of filter queries used to narrow the base result set. Filters have no impact on document scoring.

getNamedFilters

public List<NamedFilter> getNamedFilters()

Filters with associated names. These filters are treated identically to the values in getFilters() - they are used to narrow the base result set and have no impact on scoring. Additionally however, filters in this list are paired with names that allow them to be manipulated by other features. See FacetDomain.getExcludedFiltersByName() for an example.

setFilters

public void setFilters(List<Query> filters)

addFilter

public void addFilter(Query filter)

setBoostsByValues

public void setBoostsByValues(List<BoostByValue> boostsByValues)

addBoostByValues

public void addBoostByValues(BoostByValue boostByValues)

getGroupedQuery

public Query getGroupedQuery()

Returns:

overrides getMain() for group details. Results.getGroup() has to be set

This field is ignored with "hint.grouping.method=group".

getGroupedFilters

public List<Query> getGroupedFilters()

Returns:

overrides getFilters() for group details. Results.getGroup() has to be set

This field is ignored with "hint.grouping.method=group".

setBoostsByQuery

public void setBoostsByQuery(List<BoostQuery> boostsByQuery)

addBoostByQuery

public void addBoostByQuery(BoostQuery boostQuery)

clone

public QueryDefinition clone()

Specified by:

clone in class DslCloneable
