Search interface

Para indexes objects based on their type. For example, a User objects has a type field with the value “user”. Most of the search methods below ask for a type to search for (i.e. the type field acts as a filter).

The Search interface defines the following methods used for search:

Method	Description
`P findById(String id)`	Returns the object with the given `id` from the index or `null`.
`List<P> findByIds(List<String> ids)`	Returns all objects for the given ids.
`List<P> findNearby(String type, String query, int radius, double lat, double lng)`	Location-based search query.
`List<P> findPrefix(String type, String field, String prefix)`	Searches for objects containing a field (property) that starts with the given prefix.
`List<P> findNestedQuery(String type, String field, String query)`	Searches inside a nested field `nstd` (a list of objects).
`List<P> findQuery(String type, String query)`	The main search method. Follows the Lucene query parser syntax.
`List<P> findSimilar(String type, String filterKey, String[] fields, String liketext)`	“More like this” search.
`List<P> findTagged(String type, String[] tags)`	Search for objects tagged with a set of tags.
`List<P> findTags(String keyword)`	Shortcut method for listing all tags.
`List<P> findTermInList(String type, String field, List<?> terms)`	Searches for objects containing any of the terms in the given list (matched exactly).
`List<P> findTerms(String type, Map<String, ?> terms, boolean matchAll)`	Searches for objects containing all of the specified terms (matched exactly)
`List<P> findWildcard(String type, String field, String wildcard)`	A wildcard query like “example*”.

All methods accept an optional Pager parameter for paginating and sorting the search results.

Also there are a few methods for indexing and unindexing objects but you should avoid calling them directly. These methods are:

void index(ParaObject obj)
void indexAll(List<P> objects)
void unindex(ParaObject obj)
void unindexAll(List<P> objects)
