| </h1> |
| <div class="markdown level0 summary"><p>An abstract SpatialStrategy based on <a class="xref" href="Lucene.Net.Spatial.Prefix.Tree.SpatialPrefixTree.html">SpatialPrefixTree</a>. The two |
| subclasses are <a class="xref" href="Lucene.Net.Spatial.Prefix.RecursivePrefixTreeStrategy.html">RecursivePrefixTreeStrategy</a> and |
| <a class="xref" href="Lucene.Net.Spatial.Prefix.TermQueryPrefixTreeStrategy.html">TermQueryPrefixTreeStrategy</a>. This strategy is most effective as a fast |
| approximate spatial search filter.</p> |
| <p><h4>Characteristics:</h4> |
| <ul><li>Can index any shape; however only |
| <a class="xref" href="Lucene.Net.Spatial.Prefix.RecursivePrefixTreeStrategy.html">RecursivePrefixTreeStrategy</a> |
| can effectively search non-point shapes.</li><li>Can index a variable number of shapes per field value. This strategy |
| can do it via multiple calls to <a class="xref" href="Lucene.Net.Spatial.Prefix.PrefixTreeStrategy.html#Lucene_Net_Spatial_Prefix_PrefixTreeStrategy_CreateIndexableFields_Spatial4n_Core_Shapes_IShape_">CreateIndexableFields(IShape)</a> |
| for a document or by giving it some sort of Shape aggregate (e.g. NTS |
| WKT MultiPoint). The shape's boundary is approximated to a grid precision. |
| </li><li>Can query with any shape. The shape's boundary is approximated to a grid |
| precision.</li><li>Only <a class="xref" href="Lucene.Net.Spatial.Queries.SpatialOperation.html#Lucene_Net_Spatial_Queries_SpatialOperation_Intersects">Intersects</a> |
| is supported. If only points are indexed then this is effectively equivalent |
| to IsWithin.</li><li>The strategy supports <a class="xref" href="Lucene.Net.Spatial.Prefix.PrefixTreeStrategy.html#Lucene_Net_Spatial_Prefix_PrefixTreeStrategy_MakeDistanceValueSource_Spatial4n_Core_Shapes_IPoint_System_Double_">MakeDistanceValueSource(IPoint, Double)</a> |
| even for multi-valued data, so long as the indexed data is all points; the |
| behavior is undefined otherwise. However, <code>it will likely be removed in |
| the future</code> in lieu of using another strategy with a more scalable |
| implementation. Use of this call is the only |
| circumstance in which a cache is used. The cache is simple but as such |
| it doesn't scale to large numbers of points nor is it real-time-search |
| friendly.</li></ul></p> |
| <p><h4>Implementation:</h4> |
| The <a class="xref" href="Lucene.Net.Spatial.Prefix.Tree.SpatialPrefixTree.html">SpatialPrefixTree</a> |
| does most of the work, for example returning |
| a list of terms representing grids of various sizes for a supplied shape. |
| An important |
| configuration item is <a class="xref" href="Lucene.Net.Spatial.Prefix.PrefixTreeStrategy.html#Lucene_Net_Spatial_Prefix_PrefixTreeStrategy_DistErrPct">DistErrPct</a> which balances |
| shape precision against scalability. See those docs.</p> |
