Polygon data type supoort

[cevin]

A point takes intersections with multiple polygons

id	restarant_name	delivery_range
1	Pizza	( (1,1), (2,2), (3,3) )

select contains(delivery_range, point(1,1)) from table

Have you considered the geo-spatial functions https://manual.manticoresearch.com/Functions/Geo_spatial_functions#Geo-spatial-functions ? If so, can you please elaborate more on the issue with them as it's not quite clear what you suggest.

5,1	5,2	5,3	5,4	5,5
4,1	4,2	4,3	4,4	4,5
3,1	3,2	3,3	3,4	3,5
2,1	2,2	2,3	2,4	2,5
1,1	1,2	1,3	1,4	1,5

Geographic location-based spatial extent intersection search.

For example, multiple polygons with ranges of

• 1: ( (1,1), (1,5), (5,5), (5,1) )
• 2: ( (1,1), (1,4), (4,4), (4,1) )
• 3: ( (1,1), (1,3), (3,3), (3,1))
• 4: ( (1,1), (1,2), (2,2), (2,1) )

Then contains(polygon_column, point(1,3)) should return 1 , 2 and 3, contains(polygon_column, point(2,5)) should return 1.

The contains method of manticoresearch only accepts a single polygon .

So, Hopefully there can be a data type poylgon similar to MySQL or PostgreSQL.

Thanks for the explanation.

could you put all your geo data into JSON field then address it like JSON.field argument of the POLY2D function?

select contains(POLY2D(delivery_range[0],delivery_range[1],delivery_range[2],delivery_range[3],delivery_range[4],delivery_range[5]), point_attr1,point_attr2) from table
select contains(POLY2D( delivery_range[0].x, delivery_range[0].y, delivery_range[1].x, delivery_range[1].y, delivery_range[2].x, delivery_range[2].y), point_attr1,point_attr2) from table

or you do not now the amount of polygons points upfront?

or in case of multiple polygons in the attribute you could address them all with the same function and get the result

select contains(POLY2D( delivery_range[0].x, delivery_range[0].y), point_attr1,point_attr2) as cnd1,  contains(POLY2D( delivery_range[1].x, delivery_range[1].y), point_attr1,point_attr2) as cnd2, contains(POLY2D(delivery_range[2].x, delivery_range[2].y), point_attr1,point_attr2) as cnd3 from table

[tomatolog]

we also has [INDEXOF](https://manual.manticoresearch.com/Functions/Arrays_and_conditions_functions#INDEXOF()) function that could iterate JSON array and returns the index of the first element that matched

select INDEXOF( contains(POLY2D( range.x, range.y), point_attr1,point_attr2) for range in j.delivery_ranges) as val from table

It's a dynamic range, Set by the "merchant" itself, not necessarily a fixed number of points.

like:

Get all the "ranges" including the point.

This may indicate the scope of business accepted by a post office, the scope of takeout delivery for a restaurant, or the scope of business borne by an errand business.

Like PostgreSQL:

CREATE TABLE areas (
    id SERIAL PRIMARY KEY,
    shape POLYGON
);
INSERT INTO areas (shape) VALUES
    ('((0,0),(0,10),(10,10),(10,0),(0,0))'),
    ('((5,5),(5,15),(15,15),(15,5),(5,5))');

postgres=# select *,point(0,0) <@ shape as "include?" from areas;
 id |                shape                | include?
----+-------------------------------------+----------
  1 | ((0,0),(0,10),(10,10),(10,0),(0,0)) | t
  2 | ((5,5),(5,15),(15,15),(15,5),(5,5)) | f
(2 rows)

postgres=# select *,point(5,8) <@ shape as "include?" from areas;
 id |                shape                | include?
----+-------------------------------------+----------
  1 | ((0,0),(0,10),(10,10),(10,0),(0,0)) | t
  2 | ((5,5),(5,15),(15,15),(15,5),(5,5)) | t
(2 rows)
