是否有可能在 Vespa.ai 中获得匹配的“where”条件？

Question

I have a use case where I need to find out which "where" condition of the query is matched to get the result if we provided multiple conditions.

for example-

we have organization data, where we have employee name, city, technology and hobbies.

Now we have 3 conditions that are- 1. we need to get the records where the city is FOO_CITY. 2. we need to get the records where the technology is FOO_TECH. 3. we need to get the records where the hobby is FOO_BLOG.

when we write the query we get the output rows which satisfies these condition but I need to find out which condition is satisfied from all the above three.

Answer 1

You can ask Vespa to produce summary rank features which you can consume in your middle tier or in a searcher plugin.

See https://docs.vespa.ai/documentation/ranking.html .

Set of built in rank features https://docs.vespa.ai/documentation/reference/rank-features.html

Given that we have 3 fields, city, technology and hobby:

rank-profile what-matched-my-query {
    first-phase {
       expression: something 
     }
    summary-features {
      matches(city)
      matches(technology)
      matches(hobby)
    }
}
