[section query(rtree<...> const &, Predicates const &, OutIter)]
'''<indexterm><primary>query</primary></indexterm>'''
Finds values meeting passed predicates e.g. nearest to some Point and/or intersecting some Box. 

[heading Description]
This query function performs spatial and k-nearest neighbor searches. It allows to pass a set of predicates. Values will be returned only if all predicates are met.

[*Spatial predicates]

Spatial predicates may be generated by one of the functions listed below: 

* [^[link group__predicates_1gac52a6557110425d4ece53fbd6f9ff866 boost::geometry::index::contains()]], 
* [^[link group__predicates_1ga02dbb7cca47de0b921ef96af464d9590 boost::geometry::index::covered_by()]], 
* [^[link group__predicates_1ga0e92e4a20dd19185584fe85847439108 boost::geometry::index::covers()]], 
* [^[link group__predicates_1ga0aa114ab16f40c8caeb3338adba5d6da boost::geometry::index::disjoint()]], 
* [^[link group__predicates_1ga78cb2ef221b951867c591ffb51b7d8c5 boost::geometry::index::intersects()]], 
* [^[link group__predicates_1ga4a6d33e6f61ad5bff3bdee50a972d54b boost::geometry::index::overlaps()]], 
* [^[link group__predicates_1gaabce901b82af2aab10ebbd0dda12f4d5 boost::geometry::index::within()]],


It is possible to negate spatial predicates: 

* [^`! `[link group__predicates_1gac52a6557110425d4ece53fbd6f9ff866 boost::geometry::index::contains()]], 
* [^`! `[link group__predicates_1ga02dbb7cca47de0b921ef96af464d9590 boost::geometry::index::covered_by()]], 
* [^`! `[link group__predicates_1ga0e92e4a20dd19185584fe85847439108 boost::geometry::index::covers()]], 
* [^`! `[link group__predicates_1ga0aa114ab16f40c8caeb3338adba5d6da boost::geometry::index::disjoint()]], 
* [^`! `[link group__predicates_1ga78cb2ef221b951867c591ffb51b7d8c5 boost::geometry::index::intersects()]], 
* [^`! `[link group__predicates_1ga4a6d33e6f61ad5bff3bdee50a972d54b boost::geometry::index::overlaps()]], 
* [^`! `[link group__predicates_1gaabce901b82af2aab10ebbd0dda12f4d5 boost::geometry::index::within()]]

[*Satisfies predicate]

This is a special kind of predicate which allows to pass a user-defined function or function object which checks if Value should be returned by the query. It's generated by: 

* [^[link group__predicates_1ga3213772dd3e54ad03340c2ca66b4f58c boost::geometry::index::satisfies()]].

[*Nearest predicate]

If the nearest predicate is passed a k-nearest neighbor search will be performed. This query will result in returning k values to the output iterator. Only one nearest predicate may be passed to the query. It may be generated by: 

* [^[link group__predicates_1ga8772d9d3e5b12b3292f7d94d47310e3e boost::geometry::index::nearest()]].

[*Connecting predicates]

Predicates may be passed together connected with [^`operator&&()`].[heading Synopsis]

[warning Only one [^[link group__predicates_1ga8772d9d3e5b12b3292f7d94d47310e3e nearest()]] predicate may be passed to the query. Passing more of them results in compile-time error.]
