Bug 31652: Add geo-search
This patch adds geosearch to Koha (using Elasticsearch 7). ElasticSearch
search_mappings get new types to store lat/lon, which can be indexed
from MARC 034$s and 034$t. There is a small change to the DB to allow a
new value in search_field.type ENUM.
The QueryBuilder is extended to allow for building advanced
ElasticSearch Querys (eg geo_distance) that cannot be represented in a
simple string query. The UI for searching (including showing the results
on a OSM/Leaflet map) is implemented in a separate plugin
(https://github.com/HKS3/HKS3GeoSearch)
Test Plan:
* make sure you're running ElasticSearch 7
(eg via `curl http://es:9200?pretty | grep number`)
* apply patch
* got to a Framework, check Editor for 034$s and 034$t and save
* got to some books (in the correct framework) and enter some lat and lon into
034$s and 034$t (for example lat=48.216, lon=16.395)
* Run the elasticsearch indexer, maybe limited on the books you edited (-bn 123
-bn 456):
misc/search_tools/rebuild_elasticsearch.pl -b -v
* You can check if the indexing worked by inspecting the document in
elasticsearch:
* get the biblionumber (eg 123)
* curl http://es:9200/koha_kohadev_biblios/_doc/123?pretty | grep -A5
geolocation
* You should get back a JSON fragment containing the lat/lon you stored
* You can query elasticsearch directly:
* Run the following curl command, but adapt the value for lat/lng and/or the
distance (in meters)
* curl -X GET "http://es:9200/koha_kohadev_biblios/_search?pretty"; -H
'Content-Type: application/json' -d '{"query":
{"bool":{"must":{"match_all":{}},"filter":{"geo_distance":{"distance":100000,"geolocation":{"lat":48.2,"lon":16.4}}}}}}'
* To run the search via Koha, you need to either install and use
https://github.com/HKS3/HKS3GeoSearch or create a handcrafted query string:
* handcrafted query string:
*
/cgi-bin/koha/opac-search.pl?advsearch=1&idx=geolocation&q=lat:48.25+lng:18.35+distance:100km&do=Search
* HKS3GeoSearch
* install the plugin and enable it
* got to OPAC / Advanced Search
* There is a new input box "Geographic Search" where you can enter
lat/long/radius
* On the search result page a map is shown with pins for each found
