extractLuceneIndexData

public ExtendedHSearchIndexData extractLuceneIndexData(org.hl7.fhir.instance.model.api.IBaseResource theResource,
 ResourceTable theEntity,
 ResourceIndexedSearchParams theNewParams)

Specified by:

extractLuceneIndexData in interface IFulltextSearchSvc

canUseHibernateSearch

public boolean canUseHibernateSearch(String theResourceType,
 SearchParameterMap myParams)

Description copied from interface: IFulltextSearchSvc

Returns true if the parameter map can be handled for hibernate search. We have to filter out any queries that might use search params we only know how to handle in JPA. - See ExtendedHSearchSearchBuilder.addAndConsumeAdvancedQueryClauses(ca.uhn.fhir.jpa.dao.search.ExtendedHSearchClauseBuilder, ca.uhn.fhir.jpa.model.search.ExtendedHSearchBuilderConsumeAdvancedQueryClausesParams)

Specified by:

canUseHibernateSearch in interface IFulltextSearchSvc

reindex

public void reindex(ResourceTable theEntity)

Description copied from interface: IFulltextSearchSvc

Re-publish the resource to the full-text index. - During update, hibernate search only republishes the entity if it has changed. During $reindex, we want to force the re-index.

Specified by:

reindex in interface IFulltextSearchSvc

Parameters:

theEntity - the fully populated ResourceTable entity

searchNotScrolled

public ISearchQueryExecutor searchNotScrolled(String theResourceName,
 SearchParameterMap theParams,
 Integer theMaxResultsToFetch,
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails)

Description copied from interface: IFulltextSearchSvc

Query the index for a plain list (non-scrollable) iterator of results.

Specified by:

searchNotScrolled in interface IFulltextSearchSvc

Parameters:

theResourceName - e.g. Patient

theParams - The search query

theMaxResultsToFetch - maximum results to fetch

theRequestDetails - The request details

Returns:

Iterator of result PIDs

searchScrolled

@Transactional
public ISearchQueryExecutor searchScrolled(String theResourceType,
 SearchParameterMap theParams,
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails)

Description copied from interface: IFulltextSearchSvc

Query the index for a complete iterator of ALL results. (scrollable search result).

Specified by:

searchScrolled in interface IFulltextSearchSvc

Parameters:

theResourceType - e.g. Patient

theParams - The search query

theRequestDetails - The request details

Returns:

Iterator of result PIDs

everything

public List<ca.uhn.fhir.rest.api.server.storage.IResourcePersistentId> everything(String theResourceName,
 SearchParameterMap theParams,
 ca.uhn.fhir.rest.api.server.storage.IResourcePersistentId theReferencingPid,
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails)

Specified by:

everything in interface IFulltextSearchSvc

isDisabled

public boolean isDisabled()

Specified by:

isDisabled in interface IFulltextSearchSvc

search

@Transactional
public List<ca.uhn.fhir.rest.api.server.storage.IResourcePersistentId> search(String theResourceName,
 SearchParameterMap theParams,
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails)

Description copied from interface: IFulltextSearchSvc

Search the Lucene/Elastic index for pids using params supported in theParams, consuming entries from theParams when used to query.

Specified by:

search in interface IFulltextSearchSvc

Parameters:

theResourceName - the resource name to restrict the query.

theParams - the full query - modified to return only params unused by the index.

theRequestDetails - The request details

Returns:

the pid list for the matchign resources.

tokenAutocompleteValueSetSearch

@Transactional
public org.hl7.fhir.instance.model.api.IBaseResource tokenAutocompleteValueSetSearch(ValueSetAutocompleteOptions theOptions)

Specified by:

deleteIndexedDocumentsByTypeAndId in interface IFulltextSearchSvc

Parameters:

theClazz - The class, which must be annotated with Indexed

theGivenIds - The list of IDs for the given document type. Note that while this is a List
