Interface SearchManager

All Known Implementing Classes:

DecoratedSearchManager, LuceneSearchManager, ProfiledSearchManager

public interface SearchManager

A V2 interface which provides searching functionality on a search index.

NOTE: A newer alternative which also includes write, transactional, reset and snapshot behaviour is SearchIndexAccessor. It also supports custom search indexes through CustomSearchIndexRegistry or extending DelegatingSearchIndexAccessor.

WARNING: there is no default permissions checking behaviour provided. You MUST provide a search which specifies permissions checking. See SiteSearchPermissionsQueryFactory to add one yourself. See PredefinedSearchBuilder to build a pre-defined search which contains permission checking.

Method Detail

search

SearchResults search(ISearch search)
              throws InvalidSearchException

Perform a search with a given criteria.

Will throw an InvalidSearchException if some error occurred converting the search object into a search that could be performed in the back-end. Usually this is a sign that some plugin that was used to create the search is no longer available.

If the ISearch contains no ContentStatusQuery in the search query or search filter tree the result of ContentStatusQuery.getDefaultContentStatusQuery() will be added as a top level AND query.

NOTE: the search limit will be capped at SearchConstants.MAX_LIMIT and the startOffset will be capped at SearchConstants.MAX_START_OFFSET for more efficient heap usage. See SearchResults.getNextPageSearch() for pagination.

WARNING: there is no default permissions checking behaviour provided. You MUST provide a search which specifies permissions checking. See SiteSearchPermissionsQueryFactory to add one yourself. See PredefinedSearchBuilder to build a pre-defined search which contains permission checking.

Parameters:

search - the search to perform

Returns:

the results of that search

Throws:

IllegalArgumentException - if the search contains an invalid SearchQuery

InvalidSearchException - when this manager is unable to translate and conduct the specified search. Clients should just discard the search if this occurs.

search

@Deprecated
SearchResults search(SearchWithToken search)
              throws SearchTokenExpiredException,
                     InvalidSearchException

Deprecated.

since 5.10. This method on one hand is rarely used on the other hand is not efficient to implement in ES.

Perform a search against a specific version of the search index (identified by calling SearchWithToken.getSearchToken() on the specified search).

This can be useful for retrieving the next page of results after an initial search. The next page of results will be calculated from the version of the search index that the initial search was performed on.

Usage:

     SearchResults searchResults = searchManager.search(search);

     // fetch next page of results
     if (!searchResults.isLastPage())
         SearchResults nextPageOfSearchResults = searchManager.search(searchResults.getNextPageSearch());
 

If the SearchWithToken contains no ContentStatusQuery in the search query or search filter tree the result of ContentStatusQuery.getDefaultContentStatusQuery() will be added as a top level AND query.

NOTE: the search limit will be capped at SearchConstants.MAX_LIMIT and the startOffset will be capped at SearchConstants.MAX_START_OFFSET for more efficient heap usage. See SearchResults.getNextPageSearch() for pagination.

WARNING: there is no default permissions checking behaviour provided. You MUST provide a search which specifies permissions checking. See SiteSearchPermissionsQueryFactory to add one yourself. See PredefinedSearchBuilder to build a pre-defined search which contains permission checking.

Parameters:

search - a search that specifies a search token.

Returns:

the results of that search

Throws:

IllegalArgumentException - if the specified search does not contain a valid search token.

InvalidSearchException - when this manager is unable to translate and conduct the specified search. Clients should just discard the search if this occurs.

SearchTokenExpiredException - if the specified search token has expired. Clients should report this the user and / or retry the search with search(ISearch).

search

SearchResults search(ISearch search,
                     Set<String> requestedFields)
              throws InvalidSearchException

Perform a search with a given criteria, the returns searchResults only have the fields requested in the projection filled out, no other fields are valid in the searchResult. SearchResults will throw an FieldNotRequestedException if an attempt is made to access a field value that has not had it's key included in the projection Set.

Will throw an InvalidSearchException if some error occurred converting the search object into a search that could be performed in the back-end. Usually this is a sign that some plugin that was used to create the search is no longer available.

If the ISearch contains no ContentStatusQuery in the search query or search filter tree the result of ContentStatusQuery.getDefaultContentStatusQuery() will be added as a top level AND query.

NOTE: the search limit will be capped at SearchConstants.MAX_LIMIT and the startOffset will be capped at SearchConstants.MAX_START_OFFSET for more efficient heap usage. See SearchResults.getNextPageSearch() for pagination.

WARNING: there is no default permissions checking behaviour provided. You MUST provide a search which specifies permissions checking. See SiteSearchPermissionsQueryFactory to add one yourself. See PredefinedSearchBuilder to build a pre-defined search which contains permission checking.

Parameters:

search -

requestedFields - requested fields. Passing null will request all fields, and passing empty set will request none.

Returns:

the results of the search, containing only the requested fields.

Throws:

InvalidSearchException

searchEntities

List<Searchable> searchEntities(ISearch search,
                                SearchManager.EntityVersionPolicy versionPolicy)
                         throws InvalidSearchException

Perform a search with the given criteria, returning the results as a list of database entity objects. Unlike the convertToEntities(SearchResults, EntityVersionPolicy) method, the list of entities returned will not contain any nulls: search results that do not match a database record will be silently discarded.

The versionPolicy determines whether the entities returned should be the same version as stored in the index (SearchManager.EntityVersionPolicy.INDEXED_VERSION) or the latest version of the same content (SearchManager.EntityVersionPolicy.LATEST_VERSION). If you don't have a particular need to retrieve the latest version, it is recommended that you retrieve the indexed version so that any permission changes made to the document when updating it will be respected.

NOTE: the search limit will be capped at SearchConstants.MAX_LIMIT and the startOffset will be capped at SearchConstants.MAX_START_OFFSET for more efficient heap usage. See SearchResults.getNextPageSearch() for pagination.

WARNING: there is no default permissions checking behaviour provided. You MUST provide a search which specifies permissions checking. See SiteSearchPermissionsQueryFactory to add one yourself. See PredefinedSearchBuilder to build a pre-defined search which contains permission checking.

Parameters:

search - the search to perform

versionPolicy - whether to retrieve the indexed version of content found via search (recommended), or the latest version of content (not recommended)

Returns:

a list of Searchable objects representing the search results

Throws:

IllegalArgumentException - if the search contains an invalid SearchQuery

InvalidSearchException - when this manager is unable to translate and conduct the specified search. Clients should just discard the search if this occurs.

4.0

convertToEntities

List<Searchable> convertToEntities(SearchResults searchResults,
                                   SearchManager.EntityVersionPolicy versionPolicy)

Helper method to convert search results into a list of database entities. Because the search index does not update at the same time as the database, a search may contain references to entities that have since been modified or deleted from the db.

Entries that have been deleted from the database are removed from the returned list of entities, so the index of the entities in the returned list may not match the indexes of the search result it corresponds to.

The behaviour for entries that have been modified in the database varies based on the versionPolicy argument. If it is set to SearchManager.EntityVersionPolicy.INDEXED_VERSION, which is the recommended default, the returned entities will be the same version as found in the index. If it is set to SearchManager.EntityVersionPolicy.LATEST_VERSION, the latest version of the content will be returned. Using the latest version is not recommended because it can mean permissions added to the document when it was most recently updated may not be respected.

Parameters:

searchResults - the results of a search from this manager

versionPolicy - whether to retrieve the indexed version of content found via search (recommended), or the latest version of content (not recommended)

Returns:

the entities represented by that search result. List may be empty if the search returned no results, or may contain null values where the result does not map to a valid database record.

Since:

4.0

explain

default String explain(ISearch search,
                       long contentId)

Produce an explanation of the search query for the specified contentId.

searchCategorised

default <T> Map<T,List<Map<String,String>>> searchCategorised(ISearch search,
                                                                          SearchManager.Categorizer<T> categorizer)
                                                                   throws InvalidSearchException

Perform a search with the given criteria, the top results are collected per category specified by the given SearchManager.Categorizer. If the ISearch contains no ContentStatusQuery in the search query or search filter tree the result of ContentStatusQuery.getDefaultContentStatusQuery() will be added as a top level AND query.

Throws:

InvalidSearchException

6.7

scan

long scan(EnumSet<SearchIndex> indexes,
          SearchQuery searchQuery,
          Set<String> requestedFields,
          Consumer<Map<String,String[]>> consumer)
   throws InvalidSearchException

Execute Consumer.accept(T) for each search result. This method enables memory optimised implementation that doesn't need to allocate memory to hold the entire search result.

If the SearchQuery contains no ContentStatusQuery in the query tree the result of ContentStatusQuery.getDefaultContentStatusQuery() will be added as a top level AND query.
