You can use Solr's Bounding-box filter to find the records between the box but it works with single point (lat,lon) and a distance.

If you have two points then you can find the record between this box by using range query. Query could be something like :

..&fq=latField:[lat1 TO lat2] AND lonField:[lon1 TO lon2]

This is the solr query: just change the pt as a search coordinate and the distance d as a radius of a circle. fq={!geofilt sfield=coordinates}&pt=10.737845823323038,106.65631819042972&d=2.8'

each document which is indexed from solr with this schema.xml config:

< field name="coordinates" type="geohash" indexed="true" stored="true" multiValued="true" />

and document object should contain a field like this: $fields['coordinates'] = implode(',', $post->getCoordinates()->getLatLng());
