Chapter 6. Solr for Spatial Search
In the previous chapter, we discussed in depth the problems faced during the implementation of Solr for search operations on an e-commerce website. We saw solutions to the problems and areas where optimizations may be necessary. We also took a look at semantic search and how it can be implemented in an e-commerce scenario.
In this chapter, we will explore Solr with respect to spatial search. We will look at different indexing techniques and study query types that are specific to spatial data. We will also learn different scenario-based filtering and searching techniques for geospatial data.
The topics that we will cover in this chapter are:
- Features of spatial search
- Lucene 4 spatial module
- Indexing for spatial search
- Search and filtering on spatial index
- Distance sort and relevance boost
- Advanced concepts
- Quadtrees
- Geohash
