            QUESTION

            Can Elasticsearch search by geo distance and other attributes at the same time?
            Asked 2021-Jan-10 at 09:31

            In Elasticsearch, when I search by geo-distance to a point, can I at the same time filter by another attribute, such as a number being within a range, so that both filters need to be true for the result to come back?

            ...

            ANSWER

            Answered 2021-Jan-10 at 09:31

            Sure, use bool query, where you can specify multiple clauses in must and (or) filter blocks. Be aware that clauses in must block will contribute to the relevance score and clauses in filter block will not (read more about query and filter context).

            For example, query that at same time search by geo-distance with contribution to score and filter an age being within a range without contribution to score:

            Find distance from a point to the n closest polygons in Elastic Search?
            Asked 2020-Jun-29 at 18:22

            This is similar to Find closest GeoJSON polygon to point when point lies outside of all polygons in Elasticsearch but instead of returning the closest polygon, I'd like to return all documents that has a polygon closer than a particular distance (say 10 km). I'd like the distance to each polygon to be included in the result and it should be sorted by distance (ascending or descending doesn't matter).

            A comment in the referred question pointed to a github issue that has now been resolved (since Elastic Search 7.7) but I cannot seem to figure out how to do it based on the documentation.

            Update

            After reading the answer by joe I want to clarify that by "distance" I mean the closest distance to the nearest point of the polygon's border. Like what's described in this question for PostGIS.

            You could use a geo_shape query with a buffered circle which will act as an umbrella that your polygons-of-interest will intersect. If they do, they match. The only issue is that the "distance to each polygon" is somewhat arbitrary -- are we talking about the nearest point of a polygon's border? Or maybe its center?

            I've only been able to come up with an implementation of the latter but it requires a secondary center field since scripted center computation would be too onerous.

            Here's a visual:

            Aws Elasticsearch: How to change mapping type of location { lat: float, lon: float} to geo_point
            Asked 2019-Nov-28 at 07:27
            Can anyone guide me to change the mapping type of location to geo_point.?

            Service: Aws ElasticSearch (6.2 Version) Database: dynamodb

            I am using aws elastic search service to filter values based on my location. As per the documentation i have created a trigger lambda function dbtoEs which is a python code soon after the record is added its indexed.

            Since my location type in dynamodb is type Location { lat: Float lon: Float }

            When i go to Aws ElasticSearch and check in indices the mapping type for this field is also location { lat float lon float }

            As per the Elastic geo distance query (https://www.elastic.co/guide/en/elasticsearch/reference/6.2/query-dsl-geo-distance-query.html) the mapping type of location should be geo_point

            You need to create mapping before first record is indexed. In absence of mapping elasticsearch interprets the type dynamically. In this case it is float.

            Look for mapping api for elasticsearch and create mapping for geo_point field using lat longs.

            Use simple print statements to display the arguments to your equation. Some of the operations in you sin expression are different lengths -- the underlying broadcast operation (sort of the vectorized equivalent of zip) requires equal lengths.

            Referring to the ES documentation, we can sort on the base of geolocation if lat and lon are both in the same geotype field.

            You will need to create a new index with a new mapping which will contain geo point field instead of two fields (lat, long). Then, you need to index data into the newly created index. Have a look into Reindex API - will help you with moving data into the new index.

            The first approach won't work like that, as the lambda function is applied to a single row of the DataFrame and x is not a list of all observations as you expect it. For this to work, you can take the previous element index with x.name-1 and access the location in df, like so
