Counting documents with both text matching and distance to a point

Question

I have an ElasticSearch index with a list of "stores."

I want to allow customers to search for these stores both using geo_distance(so finding a point and getting stores near this place), and text matching, for example, matching the store’s name / address.

I would like to get results that meet one of these two criteria, and I would like the order of these results to be a combination of both. The stronger the text match and the closer to the point found, the higher the result. (Obviously, there will be a formula for combining the two, which need to be set up and not too worried about this part).

My problem / what I tried:

• geo_distanceis filter, and not query, therefore I cannot combine both in parts of queryrequest.

• I can use a filter bool => should(rather than a query) that matches the name or location. This gives me the results that I want, but not in order.

• I can also have, _geo_distanceas part of the proposal sort, documents closer to the ranking point above.

What I did not understand is how I take the “regular” _scorethat ElasticSearch provides to documents when performing text matches, and combine this with the rating geo_distance.

, , , ( ). , query geo_distance filter, OR, AND.

{
  function_score: {
    query: {  ... },
    functions: [
      { geo_distance function },
      { multi_match_result score },
    ],
    score_mode: 'multiply'
  }
}
