Can I join an elasticsearch index with geojson to form one index to use as point to point map?

I have an index "index_travels" which has a field "travel_from" and "travel_to". These fields are not geofields. However, I have imported a geojson file "Wards" that has a field "wardID" which is the same as "travel_from" and "travel_to".

I want to draw a point to point layer using these two data sources, but "index_travels" does not appear in point to point as a usable index for point to point.

Also, when using the layer option: configured Geojson, doing those two joins does not yield the desired results because layer style of lines is for drawing borders along the regions.

How can I go about accomplishing this?

I use Kibana v 7.8.0

Joins can not be used to display point-to-point layers.

You could try using the geo_match enrich processor to add geo_point locations directly into your index_travels index.

Thanks for the response @Nathan_Reese . From the instructions on the geo_match enrich processor, I see that the two datasets to be joined must be indexed on elasticsearch. And they both have the geolocation field.. But in my dataset the imported geojson file does not appear in index management for being indexed; And my index_travels does not have a geofield. Should I add the geojson data as I would any other dataset to be indexed in order to accomplish this?

Thanks for clarifying. You can use a match policy to join by travel_from and travel_to and the add a geo_point for each into your documents. Here is a blog post that provides some details Introducing the enrich processor for Elasticsearch ingest nodes | Elastic Blog
