Method Detail

toQuery

public abstract ExtendedSearchQuery<H,R,SC> toQuery()

Description copied from interface: SearchQueryFinalStep

Create a SearchQuery instance matching the definition given in the previous DSL steps.

Calling this method is generally not necessary as most query execution methods are also implemented by this DSL step, so for example .toQuery().fetch() can be replaced with simply .fetch().

Specified by:

toQuery in interface SearchQueryFinalStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>>

Overrides:

toQuery in class AbstractSearchQueryOptionsStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>,H,LOS,PDF extends SearchPredicateFactory,SF extends SearchSortFactory,AF extends SearchAggregationFactory,C>

Returns:

The SearchQuery resulting from the previous DSL steps.

fetchAll

public R fetchAll()

Description copied from interface: SearchFetchable

Execute the query and return the SearchResult, including all hits, without any sort of limit.

SearchFetchable.fetch(Integer) or SearchFetchable.fetch(Integer, Integer) should generally be preferred, for performance reasons.

Specified by:

fetchAll in interface SearchFetchable<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>>

Overrides:

fetchAll in class AbstractSearchQueryOptionsStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>,H,LOS,PDF extends SearchPredicateFactory,SF extends SearchSortFactory,AF extends SearchAggregationFactory,C>

Returns:

The SearchResult.

fetch

public R fetch(Integer limit)

Description copied from interface: SearchFetchable

Execute the query and return the SearchResult, limiting to limit hits.

Specified by:

fetch in interface SearchFetchable<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>>

Overrides:

fetch in class AbstractSearchQueryOptionsStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>,H,LOS,PDF extends SearchPredicateFactory,SF extends SearchSortFactory,AF extends SearchAggregationFactory,C>

Parameters:

limit - The maximum number of hits to be included in the SearchResult. null means no limit.

Returns:

The SearchResult.

fetch

public R fetch(Integer offset,
               Integer limit)

Description copied from interface: SearchFetchable

Execute the query and return the SearchResult, skipping offset hits and limiting to limit hits.

Specified by:

fetch in interface SearchFetchable<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>>

Overrides:

fetch in class AbstractSearchQueryOptionsStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>,H,LOS,PDF extends SearchPredicateFactory,SF extends SearchSortFactory,AF extends SearchAggregationFactory,C>

Parameters:

offset - The number of hits to skip before adding the hits to the SearchResult. null means no offset.

limit - The maximum number of hits to be included in the SearchResult. null means no limit.

Returns:

The SearchResult.

scroll

public SC scroll(int chunkSize)

Description copied from interface: SearchFetchable

Execute the query continuously to deliver results in small chunks through a SearchScroll.

Useful to process large datasets.

Specified by:

scroll in interface SearchFetchable<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>>

Overrides:

scroll in class AbstractSearchQueryOptionsStep<S extends SearchQueryOptionsStep<S,H,LOS,SF,AF>,H,LOS,PDF extends SearchPredicateFactory,SF extends SearchSortFactory,AF extends SearchAggregationFactory,C>

Parameters:

chunkSize - The maximum number of hits to be returned for each call to SearchScroll.next()

Returns:

The SearchScroll.
